Check Valve Type Z2S

Pilot operated double check valve type Z2S6 serves to shut-off an oil flow in one direction and allow free flow in the oppostie direction. They can also be opened in the direction of closure. These valves are mostly used :
- to relieve a working circuit under pressure
- to prevent a load from falling in the case of a line rapture
- to prevent creep movements of hydraulically stressed users.
