Projects are revised
Changed circuit functions, port sizes, coil voltages or machine designs can leave purchased valves outside the final installation scope.
Surplus industrial pneumatic controls
Sell surplus directional valves.
Move idle pneumatic stock forward.
Unused solenoid valves. Duplicate maintenance spares. Manifolds for a production line that no longer runs. We work with companies looking to sell excess industrial pneumatic directional valves.

How surplus develops
The control system changes.
The valve inventory often remains.
Pneumatic directional valves route compressed air through industrial control circuits. Stock is often tied to particular machines, electrical supplies and manifold platforms. When those requirements change, the valves held to support them can become surplus.
Platforms are replaced
New valve islands, revised controls and retired machinery can release individual valves and spares for systems no longer in use.
Stock accumulates
Duplicate ordering, changes in preferred brands and consolidated storerooms can reveal more pneumatic inventory than maintenance needs.
Before releasing stock, confirm with maintenance and controls personnel which valves remain necessary for active machinery, planned work or internal redeployment.
Identify what you have
Directional valve inventory worth discussing.
We welcome inquiries about individual valves, complete manifolds and related components. Valve function, actuation, mounting and electrical details all help establish the configuration.
Solenoid-operated valves
Single- and double-solenoid directional valves. Identify the full valve code, coil voltage and AC or DC designation, connectors and included coils.
Air-piloted valves
Pneumatically actuated directional valves. Record the function, pilot arrangement and documented operating or pilot-pressure requirements.
Manual & mechanical valves
Lever, button, pedal, roller and other actuated designs. Describe the actual operating mechanism, return arrangement and mounting configuration.
3/2, 5/2 & 5/3 functions
These designations identify port count and switching positions. Include the circuit symbol, normal state or center configuration where applicable.
Manifolds & valve islands
Multi-station assemblies with valves, bases and control interfaces. Record station count and identify each valve, end plate and electronic module.
Subbases & accessories
Mounting bases, coils, connectors, blanking plates and other identifiable parts. List items separately and document matching series when known.
Categories overlap: a 5/2 valve may be solenoid-operated and manifold-mounted. Describe each unit’s complete configuration.
Recognizable brands. Specific platforms.
Start with the manufacturer.
Keep every model suffix.
Common names in industrial pneumatic valve inventory include the manufacturers and product families below. Other brands and legacy stock are welcome in an inquiry.
SMC · Festo · Parker · Norgren · AVENTICS · ASCO · MAC Valves · Camozzi · CKD · Numatics
Brand names identify equipment only. Pneumatic Directional Valves does not claim manufacturer authorization, endorsement or affiliation.
Port size and voltage are only part of the identity.
Similar-looking valves can differ in function, pilot supply, return behavior, mounting interface and connector arrangement. Full model codes and symbols help distinguish these details.
- Photograph valve and coil markings separately.
- Copy all prefixes, suffixes and option codes.
- Record port size and thread type where known.
- Capture the pneumatic circuit symbol.
- Identify mounting bases and interface modules.
Condition and completeness matter
Separate unused stock from removed valves.
Sealed inventory, opened unused units and equipment removed from service should be described separately. Share known operating history, storage conditions and any inspection or test records.
Disclose leaks, sticking, damaged ports, corrosion, burnt coils, broken connectors, modifications and missing components. External appearance does not establish switching or sealing performance.
Keep bases, seals, coils, connectors and hardware linked to the correct valves. State when performance or compatibility is unknown.
Make assemblies understandable
A valve island is more than a row of valves.
A manifold assembly may contain different valve functions, supply zones, electrical interfaces and station accessories. Photograph the entire assembly and individual labels so its contents can be identified.
Include available drawings or station lists. State whether the assembly is complete and which modules, connectors or valves have been removed.
Do not infer compatibility from appearance.
Valves with similar dimensions or port arrangements may belong to different mounting or control platforms. Identify each component rather than describing mixed stock as a matched system.
Application suitability should be checked against manufacturer documentation. For installed equipment, testing, isolation and removal should be handled by qualified personnel.
From excess stock to a clear inquiry
Start with the inventory you already have.
A partial list, stock export or readable photos can establish the starting point. Identify which items have been counted and which remain uncertain.
Confirm the surplus
Check active machine platforms and spare requirements. Select excess quantities and inventory no longer needed for current or planned systems.
Group and identify
Sort by full model code, count quantities and note condition. Keep assemblies intact where practical and identify loose parts separately.
Discuss selling the stock
Share the details, location and timing. Inventory fit, commercial terms and packing or transport requirements are confirmed for the specific lot.
A realistic view of resale potential
Value depends on the specific stock.
Potential resale value depends on identification, configuration, quantities, condition, completeness and demand. A recognizable brand or high original purchase price does not guarantee an offer.
Preserve the details that distinguish the lot.
Retain packaging, manuals and assembly records. Avoid grouping similar-looking valves as identical without checking the full code and coil details.
A clear surplus review also helps purchasing and maintenance distinguish needed spares from stock tied to retired control systems.
Common questions
Selling surplus pneumatic directional valves
Can I inquire about used valves?
Yes. Describe prior service, why the valves were removed and any known faults. Include photos and available test records. Used or untested condition needs to be considered during review.
What if I have several functions and coil voltages?
Group by exact model and coil identification where practical. Record quantities and ratings separately, and flag mixed or unidentified stock clearly.
Can I submit complete valve islands or manifolds?
Yes. Include overview photos, station count, valve codes and interface module details. Identify missing components and provide available drawings or station records.
Should I include loose coils and subbases?
Include them as separate items with their own part numbers, quantities and condition. Identify known matching series without assuming compatibility.
What if the model or configuration is uncertain?
Start with readable labels, circuit symbols and overall photos. State which details are unknown rather than guessing function, pressure requirements or electrical ratings.
Is there a minimum quantity or guaranteed purchase?
Share the stock you have. Whether a transaction makes sense depends on the models, quantities, condition and logistics. Any offer or commercial arrangement is confirmed after review.
Put idle pneumatic controls on the agenda
Have directional valves your company no longer needs?
Unused project stock, duplicate spares or a larger manifold lot — start with the details you have.
