A valve that fits the pipe can still be wrong for the process. With used industrial valves and fittings, nominal size alone won’t confirm suitability. Pressure and temperature limits, process media, materials and connection details all matter. Listing information may also leave gaps in an item’s service history or condition.
Before committing to second-hand equipment, get clear specifications and identify what still needs checking. This guide explains how to define your requirements, check process compatibility and interfaces, and assess condition and documentation. It also shows what to include in a supplier enquiry so you can compare options more effectively. F.A. Maker supplies used pumps and valves in Australia. Confirm directly whether the valve or fittings you need are available.
Ask specific questions about prior service, storage, visible wear, maintenance records and known faults. The answers can help you assess whether an item may suit your application. The aim is a disciplined sourcing process, not a decision based on a brief listing or a matching pipe size.
Start with the line, not the listing. Whether you’re matching an existing installation or sourcing a replacement, identify what the component must do and how it connects to the pipework. Used industrial valves and fittings can appear suitable by type or size yet still be wrong for the process.
A valve controls, directs or stops flow through a system. A fitting joins, branches, adapts or changes the direction of pipework. Valve selection is about controlling process flow; fitting compatibility is about connecting the pipework correctly. For a foundational overview of industrial valves, including common types and their functions, see Wikipedia.
Record the process medium and intended duty, such as isolation, flow regulation or prevention of reverse flow. Note operating pressure and temperature, and whether the service involves a fluid or gas that could affect material selection. Capture the line size, connection type and any installation constraints, such as limited access, actuator clearance or the space between pipe ends.
Use drawings, equipment nameplates and measurements from the existing line where available. Don’t assume a stated nominal size guarantees a physical match. Ask the responsible engineer to confirm the required specifications before contacting suppliers, especially if the item will be used in a safety-critical or pressure-containing application.
Valve type can narrow the search, but it doesn’t establish suitability. The general roles below are a starting point only. Actual selection depends on process conditions and the specific valve design.
Before settling on a type, verify the required duty, operating limits, materials and connection details. A familiar valve category doesn’t prove that a particular used item will perform as required. The responsible engineer should check the specification against the process and installation before purchase.
Compare candidate items against a written specification, not just a listing title. For used industrial valves and fittings, check each field against the process design and mating pipework. Treat any missing or unclear detail as a question to resolve before purchase, not as something to assume.
Matching nominal size alone does not establish compatibility. Pressure and temperature limits, materials and connection interfaces must also suit the application.
| Specification | What to confirm |
|---|---|
| Type | Valve or fitting type and intended duty. |
| Size | DN designation plus relevant measured dimensions. |
| Pressure and temperature | Required operating range and the item’s stated limits at those conditions. |
| Material | Body and wetted-part materials, including seals where specified. |
| End connection | Flanged, threaded or other connection, with matching interface details. |
DN means nominal diameter. It identifies a standardised size designation, not necessarily the exact internal or external diameter measured on the item. PN is a nominal pressure designation, but it should not be treated as a standalone operating-pressure guarantee. Confirm the item’s documented limits for the relevant temperature and service conditions. Compare measurements with drawings or the mating component rather than relying on DN or PN alone.
Check that every wetted material is compatible with the process medium. Consider operating temperature and pressure, possible corrosion, and cleaning chemicals or procedures. These factors can affect the body, trim, seals and other components differently. Material suitability depends on the application, so have the responsible engineer check it against process requirements and available item documentation.
Identify the connection type before comparing dimensions. Flanged ends need matching flange details; threaded ends need the correct thread form and dimensions. Other connection styles also require their own interface checks. For a valve, compare face-to-face length with the available pipe gap, and check actuator mounting and clearance where relevant. If the listing lacks detail, ask for measurements or drawings and compare them with the mating equipment.
Where a used item forms part of plant, Safe Work Australia’s guidance can help buyers assess condition and purchasing risk. F.A. Maker supplies used pumps and valves. Confirm current valve stock and ask separately whether the fittings you need are available. A clear specification brief can make the enquiry more useful. You can contact F.A. Maker about used valves.
A used valve may be a practical sourcing option when a suitable item is available. The trade-off is uncertainty: service history, storage conditions or maintenance records may be incomplete. A new valve may come with clearer product documentation, but neither its label nor its new status alone proves suitability for your process.
Condition descriptions such as “good”, “tested” or “unused” are starting points, not evidence. Ask what was inspected, how it was assessed and whether records are available. For used industrial valves and fittings, base your decision on item-specific details rather than a general description. A visual check can reveal obvious concerns, but it can’t confirm pressure integrity or internal condition.
Begin with external condition. Look for body corrosion, impact damage, deposits, damaged coatings, stem or handwheel issues, and signs of leakage around joints or seals. Request clear photographs of the nameplate, markings, both ends and any visible defects. These checks can reveal questions to resolve, but they don’t establish operational fitness.
Don’t dismantle, pressurise or operate equipment unless the work is within the competence of the people involved and suitable controls are in place. Pressure testing and other verification should be scoped and completed by qualified personnel where required. Ask for the method, results and limits of any reported test rather than treating “tested” as complete assurance.
Ask for the manufacturer, model, serial number or other identifying marks where present. Request available maintenance, service, test and previous-duty records. Prior service matters: a valve used with a clean utility may have a different history from one exposed to corrosive media. Ask whether it was decontaminated and how it was stored, as age and storage can affect seals and other components.
Clarify exactly what has and hasn’t been inspected, tested or refurbished. If a record is unavailable, note the gap and consider what further assessment your application requires. Don’t infer compliance, certification or performance from appearance, a condition label or a seller’s brief description. Have the responsible engineer determine whether the available evidence is adequate for the intended service.
To compare a used valve with a new one, weigh the available documentation and verification needs alongside suitability and availability. The right choice depends on the item’s evidence and your process requirements, not on the word “used” or “new” alone.
A structured enquiry helps suppliers check what you need and helps you identify gaps before purchase. Follow these steps when sourcing used industrial valves and fittings, and keep the supplier’s answers with your purchasing records.
A useful supplier enquiry explains what the component must do, how it connects and what evidence you need to assess it. Ask which details are confirmed from the item itself and which are estimates or need further verification. This makes uncertainty visible early and gives your responsible engineer a clearer basis for review.
F.A. Maker supplies used industrial equipment, including pumps and valves. Confirm current valve stock, item-specific condition and documentation directly, and ask separately about fittings availability. If your project involves moving plant, F.A. Maker also offers machinery relocation services.

F.A. Maker is an Australian, family-owned supplier of used industrial processing equipment, including pumps and valves. The Maker family business dates to the 1920s, and the company supplies used equipment nationally. Its confirmed range includes valves, but a particular valve may not be currently available, and fittings availability should be confirmed directly.
When sourcing used industrial valves and fittings, treat supplier contact as a specification check, not just a stock enquiry. Give the supplier enough detail to compare an item with your application, then verify the individual equipment’s identity, condition and documentation before deciding. If you need fittings as well as a valve, ask about their availability separately.
Ask whether an item matching the required type and specification is currently available. If a potential match is identified, confirm its identifying details, such as manufacturer, model or markings where present, along with the item-specific condition description and available records.
Be clear about the evidence you need. Ask what is known about prior service, what has been inspected and whether test or maintenance records exist. Clarify anything not established by the available information. Don’t assume inspection, testing, refurbishment or compliance status is included or guaranteed. Verify each point for the specific item.
Keep the enquiry concise, but include enough technical detail for a meaningful response. Summarise the process application and duty, then separate essential requirements from preferences. Include the valve type, size, connection details, materials, operating limits, actuator needs and required quantity where known. If you’re seeking a fitting, describe its function and interface, then ask whether it is available.
Photographs or drawings can help explain an existing installation. Show the connection faces and surrounding space, and include measured dimensions where possible. Make clear which specifications your engineer has confirmed and which need checking against the equipment. This helps avoid treating an approximate match as a verified fit.
Contact F.A. Maker about its used pumps and valves. Share your application and specification brief, then confirm current stock, condition details and documentation directly before proceeding. For fittings, ask specifically whether the items you need are available.
A sound purchase starts with a clear application brief. Confirm the process duty, operating limits, materials and connection interfaces, then compare those requirements with the specific item’s details. For used industrial valves and fittings, nominal size or a broad condition label isn’t enough to establish a match. Check available service history, inspection evidence and documentation before committing, and clarify any gaps with the supplier.
F.A. Maker is an Australian, family-owned supplier of used industrial equipment, including pumps and valves. The Maker family business dates to the 1920s. Confirm current valve stock and ask separately whether the fittings you need are available, along with item-specific condition information and records.

They may be suitable, but safety depends on the specific valve, its condition, service history and intended application. Review available records, inspect visible condition and have a competent person determine whether further assessment or testing is needed. A seller’s condition label or a visual check alone can’t confirm pressure integrity or suitability. Before installation, the responsible person should assess the item against the process and site requirements.
Check the existing line drawings, valve markings and measured interfaces, then confirm the selection with the responsible engineer. DN is a nominal diameter designation, not necessarily the exact diameter measured on the valve. PN is a nominal pressure designation, not a complete statement of operating limits. Verify the item’s documented pressure and temperature limits for the intended service, along with connection dimensions and valve type.
Possibly, but suitability must be established for the specific process and site requirements. Check wetted materials, seals, prior service, cleaning compatibility, surface condition and available records. Ask whether the valve’s history and condition can be substantiated, and whether it meets your facility’s hygiene and quality requirements. Don’t assume stainless steel, an unused label or a general description makes a valve suitable. Have the responsible technical team assess the evidence.
Check the body for corrosion, impact damage, deposits and visible evidence of leakage. Look over the stem, handwheel or actuator interface, end connections, nameplate and markings. Request photographs that show these areas and any defects. Ask for identifying details, prior-duty information and available maintenance or test records. Visual inspection can reveal concerns, but it doesn’t verify internal condition or pressure integrity. Any dismantling or testing should be handled by competent personnel using appropriate controls.
A valve controls, directs or stops flow through a system. A pipe fitting joins, adapts, branches or changes the direction of pipework. They serve different functions, even when installed in the same line. For example, a valve may isolate equipment for maintenance, while a fitting connects pipe sections or adapts an interface. A suitable valve still needs compatible end connections to fit the surrounding pipework.
Compare the valve’s end connection and measured dimensions with the mating pipework or equipment. Check whether the ends are flanged, threaded or another type, and verify the relevant flange details or thread form. Confirm face-to-face length, available installation space and actuator clearance where applicable. Don’t rely on nominal size alone. Drawings, clear photographs and measurements can help, but have the responsible engineer confirm the match before purchase.
F.A. Maker’s confirmed equipment offering includes used pumps and valves, but a dedicated fittings inventory isn’t confirmed. Ask directly whether the specific fitting you need is currently available. Provide its function, dimensions, connection details and required quantity, and confirm any item-specific condition information or records. Availability can vary, so don’t assume a fitting is in stock based on a general equipment category or a valve listing.
