Jiangsu Bell Valve Explosion proof Electric actuator DZB 10

Description :

　　1DZB10Explosion proof electric actuatorOverview

　　Multi turn valve electric device is a driving equipment that enables valve opening, closing, or regulating control. Z-type electrical installation is suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, water gates, etc. Can be used for both open stem valves and concealed stem valves.

　　This series of electrical installations has the characteristics of comprehensive functionality, reliable performance, advanced control system, small size, light weight, and easy use and maintenance. Valves can be remotely controlled, centrally controlled, and automatically controlled. Widely used in industries such as power, metallurgy, petroleum, chemical, papermaking, and wastewater treatment.

　　The performance of this product meets the requirements of JB/T8528-1997 "Technical Conditions for Electric Devices of Ordinary Valves". The performance of the explosion-proof type complies with the provisions of GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d "", and JB/T8529-1997 "Technical Conditions for Explosion proof Valve Electric Devices". Multi turn electric devices are classified by protection type: outdoor type and explosion-proof type;

　　Divided by control mode: there are conventional type, integral type, and integral adjustment type;

　　Divided by connection type: there are torque type, power station type, and thrust type
