BDB - Bolt-fitting double counterbalance valves for open center
The BDB balancing valves 3/8 BSPP version (3/8 G) allow a load to be kept blocked, the built-in relief valve protects the system from overpressures in the cylinder by sending the oil to the drain.
Double acting overcenter valve with bolt connection
Overcenter valves are particularly used on all cylinders that maintain suspended loads.
The hardened and ground shutter and sealing seat guarantee the perfect sealing of the valve, the manifold in which they slide is made of high quality steel with zinc treatment. Normally they are calibrated 1.3 times the maximum pressure induced on the load.
