4-20 ma 360 degree rotary electric valve actuator z20-18t z30-18t

 

The multi-turn valve devices is referred to as Z type intelligent integrated devices, which is a driving device for opening, closing or adjusting the valve. This type of device is suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, sluice gates, etc. It can be used for both open and deep rod valves.

This series of device has the features of full function, reliable performance, advanced control system, small size, light weight, convenient use and maintenance. It can implement remote control, centralized control and automatic control of the valve, which is widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other industries.

The performance of this product complies with the provisions of JB/T8528-1997 "Technical Conditions for Ordinary Valve Electric Devices". Ex-proof performance meets GB3836. 1-2000 "General requirements for electrical equipment for explosive gas atmospheres", GB3836. 2-2000 "Electrical equipment for explosive gas atmospheres, part 2, Ex-proof type "d"" and JB /T8529-1997 "Technical conditions for Ex-proof valve electric devices".

Multi-turn devices are classified according to the type of protection: outdoor type and Ex-proof type.

According to the control method: conventional type, intelligent integrated integration type and intelligent integrated regulation type.

According to the connection type, there are torque type, power station type and thrust type.
