BSI - Single counterbalance valve for open center, single flanged version
The BSI counterbalance valves (Gas thread) allow you to keep a load locked , the built-in relief valve protects the system from overpressure in the cylinder by sending the oil to drain.
Overcenter valves are particularly used on all cylinders that hold suspended loads. They are built in various sizes with threads starting from 1/4 BSPP (1/4 G) up to 1/2 BSPP (1/2 G).
The hardened and ground shutter and sealing seat guarantee perfect sealing of the valve, the manifold in which they slide is made of high quality galvanized steel. Normally 1.3 times the maximum pressure induced on the load are calibrated.
