ルブアクチユエータ。 It is equipped with a joint connected to an operating shaft for adjusting the opening of the valve, a reciprocating member coupled to the joint, and a motor that advances and retracts the reciprocating member via a reciprocating mechanism, and presses the joint via a piston. a spring that can be biased to drive the operating shaft in the direction of shutting off the valve; and a pneumatic supply system that normally compresses the spring via the piston to render it inactive with respect to the joint; A solenoid valve attached to the pneumatic supply system and when the power supply to the motor is stopped, the solenoid valve is opened to exhaust the air from the pneumatic supply system, so that the spring is biased to press against the piston. An emergency automatic shutoff type valve actuator characterized by being equipped with an automatic control system.
