Pinch Valves - Pumps, Valves, Piping and Fittings
Pinch valves use a flexible elastomer sleeve that closes by compression, providing a full-bore flow path and reliable isolation. In marine service, they are mainly used for abrasive, corrosive, contaminated, sludge, slurry, and wastewater lines.
ProShipWorks provides end-to-end support to source and supply Pinch Valves for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | No single universal marine standard applies to all pinch valves. Product design, pressure testing, materials, and quality systems are normally supported by manufacturer specifications and applicable ISO 9001 quality systems. Marine installation may also require compliance with vessel piping, SOLAS, and owner specifications. |
|---|---|
| Class Approval | Type approval or product acceptance is manufacturer- and project-specific. DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK may accept pinch valves for marine installation when supported by approved drawings, material documentation, pressure tests, and application data. |
Installation, Maintenance & Safety Information
| Installation Notes | Install in the flow direction specified by the manufacturer, with correctly rated flanges or threads and adequate pipe support. Verify sleeve compatibility, pressure rating, actuator air supply, and access for sleeve replacement. Do not use the valve outside its approved pressure, temperature, or vacuum limits. |
|---|---|
| Maintenance Tips | Inspect the sleeve for wear, cracking, swelling, and leakage at scheduled intervals. Check actuator operation, air lines, supports, and flange or threaded connections. Replace the sleeve when wear limits are reached and keep a spare sleeve suitable for the service medium. |
| Safety Notes | Isolate, depressurize, drain, and lock out the line before inspection or maintenance. Confirm that the valve is suitable for the fluid, pressure, temperature, and vacuum conditions. Treat pneumatic actuators as stored-energy devices and follow vessel isolation and permit-to-work procedures. |
