BSB - Bolt-fitting Single counterbalance valves for open center
The counterbalance valves allow to keep a load locked , the built-in relief valve protects the system from overpressure in the cylinder by sending the oil to drain.
Single acting non-compensated counterbalance valves for in-line applications
Overcenter valves are particularly used on all cylinders that maintain suspended loads.
The hardened and ground obturator and sealing seat ensure 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.
