Multi-turn electric valve actuator is a driving device for valves to realize opening, closing or modulating control. It is suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, water gates, etc. It can be used for rising stem valves and non rising stem valves. This series of electrical equipment has the characteristics of complete functions, reliable performance, small size, light weight, and convenient use and maintenance. Remote control, centralized control and automatic control can be implemented on the valve. Widely used in electric power, metallurgy, petroleum, chemical industry, papermaking, sewage treatment and other industries.
Multi-turn electric actuators are classified according to protection types: outdoor type and explosion-proof type;
According to the control mode: there are intelligent on-off type and intelligent modulating type;
According to the connection type: there are torque type, power station type and thrust type.
The performance of this product conforms to the provisions of JB/T8528-1997 "Technical Conditions for Ordinary Electric Valve Actuator". The performance of the explosion-proof type complies with GB3836.1-2000 "Electrical Equipment for Explosive Gas Atmospheres Part 1: General Requirements", GB3836.2-2000 "Electrical Equipment for Explosive Gas Atmospheres Part 2: Flameproof Type "d"" and The provisions of JB/T8529-1997 "Technical Conditions for explosion-proof Electric Valve Actuator "d".
