Project revisions
Changed piping, materials or process requirements can leave purchased valve assemblies outside the final design.
For companies with excess process equipment
Sell your surplus industrial control valves.
A canceled project. A process redesign. Spare valves for equipment that is no longer running. Put your excess control valves, actuators and positioners on the agenda for a surplus review.
Discuss your surplus control valves →Start with an inventory list, nameplate photos or the details you already have.
From reserved stock to genuine excess
Processes change. Valve inventory can get left behind.
Control valves are often purchased for a specific service, operating range or equipment package. When the process changes, a carefully specified spare may no longer support an active asset. Identifying that mismatch is the first step toward releasing excess inventory.
Plant upgrades
Replacement equipment and revised control strategies can strand spare valves and accessories for the previous installation.
Storeroom consolidation
Combining inventory locations can reveal duplicate spares, unassigned assemblies and stock tied to retired equipment.
Review active equipment and maintenance requirements before declaring stock surplus. Separate critical spares from items your company is ready to sell.
Inventory to include in your inquiry
Complete assemblies, individual valves and related components.
Identify the valve design and describe what is included. A body alone, an actuated valve and a fully equipped control assembly are different inventory items.
Globe control valves
Single-port, cage-guided, angle-pattern and other globe-style designs. Include trim identification and available sizing or specification sheets.
Rotary control valves
Segmented ball, characterized ball, eccentric plug and butterfly valves configured for modulating service. Identify the exact model and assembly configuration.
Three-way control valves
Mixing and diverting assemblies. Record port arrangement and intended service from the original documentation when available.
Specialized service assemblies
Valves specified for demanding temperature, pressure, noise or erosion conditions. Include documented materials and trim details rather than assumptions.
Actuators and positioners
Pneumatic diaphragm or piston actuators, electric actuators and positioners. List model numbers, accessories and known operating configuration separately.
Bodies, trim and spare parts
Valve bodies, plugs, cages, seats, stems and repair components. Preserve part numbers and identify whether items are loose, installed or incomplete.
Manufacturer identification
Start with the nameplate. Keep the full model.
Your lot may include equipment carrying names such as:
Fisher · Masoneilan · SAMSON · Flowserve · Valtek · Neles · Spirax Sarco · Bürkert
Brand names are provided for equipment identification only. No manufacturer affiliation or authorized distributor status is implied.
A familiar brand is only the starting point.
Nominal size, pressure class, body material, trim, connections and actuator configuration distinguish one valve from another. Similar-looking units should not be grouped as identical without checking their identification.
Photograph the valve, actuator and positioner plates separately. Include serial numbers and original valve tags where available, keeping each set of records with the correct assembly.
Build a clear inventory picture
The specification is part of the story.
A useful surplus list describes both the hardware and the available documentation. Share known specifications, mark unknowns clearly and distinguish nameplate information from assumptions.
Describe condition without overstating it.
Separate unused stock, unused equipment with storage wear, used removals, rebuilt units and untested inventory. Disclose corrosion, missing components, damaged connections, leakage history or known actuator and positioner faults.
Include available service, rebuild and test records. Removal from a working line is helpful history, but it does not establish present condition or suitability for another process.
Preserve what makes the lot identifiable
Keep the assembly and its records together.
Avoid separating tagged accessories or mixing loose trim from different valves. Record missing parts, and state whether an actuator or positioner is installed, included loose or absent.
Original specifications can help explain the assembly, but a pressure class alone does not establish suitability for every temperature or process. Actual configuration and service requirements need technical review.
Document previous service.
For used equipment, note the process medium and any known cleaning or decontamination status. Identify remaining residues or unknown service history before packing or transfer.
Qualified personnel should handle isolation, removal and any testing. Protect exposed connections and nameplates during storage, and disclose issues rather than concealing them beneath fresh paint or packaging.
A practical way to begin
Turn idle valve stock into a defined surplus lot.
Confirm what can be released
Check active assets, maintenance needs and planned projects. Identify the assemblies and spare quantities no longer required.
List and photograph the inventory
Use an existing spreadsheet or clear photos. Group by exact configuration, note condition and identify included accessories.
Discuss selling your stock
Share the inventory, location and timing. Equipment fit, commercial terms and logistics responsibilities can then be discussed for the specific lot.
A realistic view of resale potential
Value depends on the specific valve and its condition.
Configuration, materials, completeness, documentation, condition and demand all influence resale potential. Original purchase cost alone does not determine an offer.
Make uncertainty visible.
A complete specification and readable identification can make a lot easier to assess. Missing records do not prevent an inquiry, but unknown trim, service history or operating condition should be stated clearly.
Any purchase decision, pricing or transaction arrangement depends on review. An inquiry does not guarantee an offer or acceptance of every item.
Common questions
Selling surplus industrial control valves
Can I inquire about unused and used control valves?
Yes. Identify condition for each item and include available service history for used equipment. Separate unused stock from rebuilt, used and untested units.
Can I include actuators and positioners separately?
Yes. List their own model numbers, quantities and condition. State whether mounting hardware and accessories are included, and avoid assuming compatibility with a valve based on appearance.
What if I only have photos and valve tags?
Start with those. Clear photos of the complete assembly and each nameplate are useful, along with approximate quantities, location and any available specifications.
Should I dismantle the valves before submitting details?
An inquiry can begin with the assembly as it is. Share existing identification and records. Any disassembly or inspection should be determined and performed by qualified personnel.
Can older models or incomplete assemblies be included?
Yes. Identify the equipment and disclose missing parts or unknown details. The specific model, condition, completeness and demand need individual review.
Do all valves in a lot need to be identical?
No. Mixed lots can be described item by item. Separate sizes, pressure classes, materials, trim and actuator configurations so the inventory is represented accurately.
Give excess equipment a next step
Have control valves your company no longer needs?
Start with the unused project stock, retired assemblies and surplus spares already in your inventory.
