Oleodinamica Marchesini V0055 VBPDE CYL double pilot-operated check valve

The Oleodinamica Marchesini V0055 is a cylindrical double pilot-operated check valve for holding a hydraulic cylinder in either direction. It has G 3/8 ports, a maximum flow of 45 L/min and a maximum operating pressure of 350 bar. The pilot ratio is 1:5 and cracking pressure is 3 bar.

The valve permits flow toward the actuator and blocks reverse flow until pilot pressure opens the check. Its zinc-plated steel body houses hardened and ground steel internals and NBR seals.
