Abstract

PROBLEM TO BE SOLVED: To simplify structure and to hold the intermediate opening of a valve by a method wherein through the force of a resilient substance generated in linkage with an electric motor and a balance between a motor brake force and a delicate drive force, the opening of a valve is regulated. SOLUTION: A set value, such as a flow rate of fluid, is set at a preset part 7. A flow rate of fluid in a line is detected by a sensor 13, an output therefrom is actually measured by a detecting part 8, and when the actual measurements and set value coincide with each other, a valve opening is held. In this case, a switching control part 10 and a drive control part 11 are operated, and in addition to the brake force of an electric motor 5, a slight drive force is exerted on an output shaft through a deceleration mechanism 4. A balance among a resilient force, a brake force, and a drive force is kept against the resilient force of a resilient substance 3 to energize the output shaft 2 in a closing direction, and the output shaft is stopped. In which case, when service interruption and an emergency stop occur during release of a valve A, energization is disconnected and the output shaft 2 constrained by the motor 5 fully closes a valve A through the resilient force of the resilient substance 3.
