EP4000 Series electrical and gas valve locator
EP4000 Series electrical and gas valve locator
With spring load control, select the corresponding spring after can get the most
suitable for the actuator positioner.
2, Small gas consumption
Gas consumption is small, large capacity of the amplifier.
3, Can choose the output characteristic
Because of the feedback mechanism of CAM device, so you can choose output
characteristic features.
First, Product Overview
EP4000 electricity - gas valve positioner is made in introducing foreign technology.
it with the regulator, constitute a closed loop control circuit. The controller output
Electrical signal conversion to drive the regulator gas signal, at the same time,
according to the control valve to open for position feedback, the regulator can correct
positioning.
