を特徴とする残圧排気弁。 This is a pilot type switching valve that is connected to a circuit that locks the actuator at the center position of a closed center type 3-position directional control valve, etc., and outputs an output against the elasticity of a return spring using pilot pressure taken out from a pressurized air supply path. A residual pressure exhaust system characterized in that the output port is located at a position that blocks the exhaust port from the exhaust port, and when the pilot pressure decreases, the output port is switched to a position where the output port is communicated with the exhaust port by the elasticity of the return spring. valve.
