Multi-turn valve electric actuator, known by the name of Z-type, which is used for opening, closing or adjusting the valves, is an essential actuating device which can be used for remote control, centralized control and self control to the valves, with the features of comprehensive function, reliable performance, advanced control system, small volume, light weight, convenient application and maintenance and so on. It can be applicable to the valves, whose open-close parts will move in a straight line, such as gate valve, stop valve, diaphragm valve, anchor gate, water gate valve and so on.
The actuator can be used in the industries like electric power, metallurgy, petroleum, chemical engineering, paper-making, sewage disposal and so on.
There are many types for multi-turn electric actuator: outdoor type, explosion-proof type, integral type, integral-regulation type, integral explosion-proof type, integral-regulation explosion-proof type and so on. It can be divided into torque type and thrust type according to the connection type.
The performance of the product shall conform to the specification in JB/T8528-l997 Technical Condition for Common Valve is Electrical Devices. The performance of the explosion-proof product shall conform to the specifications in GB3836.l-2000 The Electrical Equipment used in Explosive Gas Atmosphere: the first part: General Requirements, GB3836.2-2000 The Electrical Equipment used in Explosive Gas Atmosphere:the second part:Explosion-proof type d, and JB/T8529-1997 Technical Condition for Explosion-proof Valve·is Electrical Devices. And it has passed the verification of National Quality Supervision &Testing Centre for Explosion-proof Electrical Products, and has got the Conformity Certificate of Protection of the whole series. And we have got the manufacturing license of industrial products approved by General Administration of Quality Supervision,Inspection and Quarantine.
