Z-type electric actuator

1.1 Product Overview

Multi turn valve electric device, abbreviated as DZW or Z-type electric device. It is a driving device that enables the opening, closing, or regulating control of valves. Suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, water gate valves, plug valves, etc.

This series of electric devices has the characteristics of full functionality, reliable performance, control system *, small size, light weight, and easy use and maintenance. Valves can be controlled on-site, remotely, and automatically.

The performance of this product meets the requirements of JB/T8528-1997 "Technical Conditions for Valve Electric Devices". The performance of the explosion-proof type complies with GB3836.1-2000

The provisions of "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".

The DZW multi turn series is divided into outdoor type and explosion-proof type according to the protection type.

The DZW multi turn series is divided into basic type, explosion-proof type, integral type (switch type/regulating type), integral explosion-proof type, and bus control according to the control mode

Type.

The DZW multi turn series is divided into torque type, power station type, and thrust type according to the connection type.

1.1 Working environment and main technical parameters

Power supply: (conventional three-phase) 380V, 50HZ, (single-phase power supply) 220V, 110V, (special power supply) 400V, 415V, 440V, 660V Environmental temperature: -20~+60 ° C (special requirements can reach -20~+80 ° C)
