Flangiable Single Pilot Operated Check Valve
Single pilot operated check valve designed for direct flange mounting to a cylinder or manifold face. The 4-bolt flange pattern eliminates hose connections at the valve-to-cylinder interface, reducing the risk of external leakage and minimising plumbing complexity.
Available in 3/8" and 1/2" BSPP work port sizes with an aluminium body as standard. A zinc-plated steel version is also available — contact FPD for details.
