Non-Leak Coupler

Pilot Check Valve Model 

Non-leak coupler with pilot check valve has non-leak function and pilot check valve. Pilot check valve makes a smooth connection and disconnection of coupler with no reaction force, since it can hold the pressure at fixture side even when the supply of pressure is stopped with coupler connected condition.

Pressurization Separated Model 

Pressurization separated non-leak coupler has non-leak function. The coupler can be disconnected even under pressurization. With non-leak function, the pressure at fixture side can be retained. The coupler can be disconnected from a hydraulic source even with pressure retained in the actuator.
