Counterbalance valves are used to keep a load locked, the built-in relief valve protects the system from overpressure in the cylinder by draining the oil.
Overcenter valve BDAY (Gas thread) double-acting uncompensated for in-line applications, for open center
Overcenter valves are particularly used on all cylinders holding suspended loads.
They are manufactured in various sizes with threads from 1/4 BSPP ( 1/4 G ) up to 1/2 BSPP ( 1/2 G ).
The hardened and ground obturator and sealing seat guarantee the perfect sealing of the valve, the manifold in which they slide is made of high quality steel with galvanising treatment. Normally they are set at 1.3 times the maximum pressure induced on the load.
