Dual Pilot Operated Check Valve
Dual-circuit providing pilot-operated check functionality on both the A and B lines simultaneously. When the circuit is pressurised in either direction, the pilot signal from one side opens the check on the opposing line — enabling full cylinder control with load-holding in both directions.
The block-body format, port range, and performance characteristics mirror the POC-1 series.
