Multi-turn valve electric device, commonly known as z-type; for open and close parts to do linear motion of the valve, such as gate valve, globe valve, diaphragm valve, plunger valve, gate valve. Used for valve opening, closing or adjustment. Is the valve to achieve remote control, centralized control and automatic control of the essential drive device; they have full-featured, reliable performance, advanced control system, small size, light weight, easy maintenance and so on. Widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other departments.
  Main technical characteristics
● Input voltage range: AC340V ~ 420V.
● Power supply wiring: three-phase two-wire or three-phase four-wire system.
● can automatically correct the phase sequence of the three-phase power supply and the correct implementation of the valve on and off control, the user can freely access the electric actuator three-phase power supply.
● The input / output signal channels are optically isolated (withstand 2000V surge voltage).
● position feedback 4 ~ 20mA signal load resistance: 50Ω ~ 700Ω, accuracy: 0.5%: three potentiometer adjustment technology can be a good tuning 4 ~ 20mA feedback signal, greatly
  Simplify the adjustment process.
● Positive action / reaction selection is done via the DIP switch on the module.
● can detect the lack of three-phase power supply. When the power supply is missing, LED lights up the alarm, automatically prohibit the actuator - cut electric operation, until the power supply three-phase
  Electricity is normal.
● If the input signal is lost, the actuator will keep the valve in place according to the user's prior code selection on the module, or move to the fully open position of the valve, or
  Action to the valve full clearance position.
● Operating temperature range: -40oC ~ +70oC.

Model specifications

Ordering instructions

   ● Please press the model to indicate the model, open and close the required torque must be separately stated, if not specified according to the provisions of the factory provided.
   ● The environment has an explosive gas must be described, and must comply with the instructions, the book explosion-proof mark requirements.
   ● Please specify the connection size standard, stem diameter and extension length, if the connection size and the instructions do not match, can be resolved with the factory.
   ● Handwheel turns clockwise to close the valve, as opposed to this.
   ● Thrust type stem nut thread is generally processed by the user, the factory only processing a prefabricated hole. For factory processing, please provide the size of the thread.
   ● The factory also according to user requirements, to provide other speed of the electric device.
