Proper selection of electric valve equipment is essential to avoid overloading (operating torque is higher than control torque).
Multi-turn electric valve actuator, referred to as Z-type electric equipment, is the driving device for the valve to be opened, closed or dispatched. Z-type electric valve actuator is suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, penstocks, etc. Can be used for open rod valves or for dark rod valves. Multi-turn electric valve actuator is divided according to the type of protection: outdoor type and explosion-proof type. According to the control method: there are regular type, all type and all scheduling type. According to the connection type: there are torque type, power station type and thrust type.
Quarter turn electric valve actuator, referred to as Q type electric equipment. It is the driving device for the valve to open, close or dispatch control. It is suitable for valves with 90 degree rotation such as butterfly valve, ball valve, plug valve and damper. Quarter turn electric valve actuator can be divided into outdoor type and explosion-proof type according to the type of protection: according to the control method, it can be divided into regular type, whole type and all scheduling type.
The valve electric actuator is a device that can complete the program control, self-control and remote control of the valve. The movement process can be controlled by the stroke, torque or axial thrust.
