Cartridge Single Pilot Operated Check Valve
Compact cartridge-format single pilot operated check valve, designed to screw directly into a standard machined cavity in a manifold or valve block. It provides pilot-released load-holding within the manifold envelope, without external plumbing between the valve and block.
The performance graph shows two curves — V1 to C1 (free-flow direction) and C1 to V1 (pilot-opened direction) — confirming the valve's behaviour under both conditions.
