Manually executing agency of the side-mounted handwheel is fitted

The side of the automatic actuator can be used worm drive, and also can be leveraged transmission mode.
Selection of top-loading or side-mounted handwheel implementing agencies should facilitate the operational considerations. When the control valve installation location, or valve side there is no room, the choice of the top-mounted handwheel actuators, and other occasions can be used side-mounted handwheel implementing agencies. Hand wheel in order to prevent misuse of the rotation, you can set the security locking device, for example, the pin fixed handwheel Limit, or top, hold hands with a small locking wheel axle.
To provide the information of the valve position, the implementing agency of the handwheel is set scale display device for the display of valve position
And other information.direct acting solenoid valve
To facilitate manual operation and automatic operation switch is normally set the clutch and switching means. When the manual position, the hand wheel with automatic actuator stem connection; when the automatic position, the hand wheel and automatic actuator stem decoupling does not affect the action of the automatic actuator.
Other implementing agencies as well as rack and pinion actuators, it is commonly used in the rotary control valve, due to the backlash caused by hysteresis, so for position control and control less demanding situations.solenoid valve actuator
