Single acting overcenter valve, for open center
Overcenter valves are particularly used on all cylinders that hold 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 zinc treatment. Normally they are set at 1.3 times the maximum pressure induced on the load.
