EP4000 Series electrical and gas valve locator | |
|
| 1.Suitable for small capacity and large capacity of actuators 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. | |
