Non-leak function and pilot check valve of the pilot check valve models maintains pressure on the fixture side and enables a smooth connection and disconnection with no reaction force even when the pressure supply is stopped in the coupler connected state.
Pressurization separated non-leak coupler is equipped with non-leak function and can be disconnected even under pressurization. With non-leak function, the pressure on the fixture side can be completely maintained. The coupler can be disconnected from a hydraulic source, holding pressure in a actuator.
The coupler can be disconnected under pressure and its air non-leak function allows for holding the pressure on the fixture side. The air pressure in actuators on the fixture can be maintained even after the coupler is disconnected from the air source.
