EP6000 series electrical and gas valve locator

Column：Technical article Time：2023-08-25
1, Suitable for small capacity and large capacity of actuators.
2, Amplifier, gas consumption is small, large capacity.


First, Product Overview
EP6000 series of electric valve positioner and actuator, 4 ~ 20 mA DC input the  signal output of air pressure, the control action of the actuator. At the same time  according to the stroke of the actuator feedback, so that the actuator stroke can  accurate positioning according to control signal. EP6000 series electric valve  positioner can be used for single action and double action type actuator.

Second, Technical Data

SeriesEP6000
Input signal4-20mA DC
Process control can be carried out
Adjustment range：4-12、12-20mA DC
Input impedance250Ω~±5% at 25℃
Output characteristicLinear (standard)
AmplifierSingle action type actuator and double action type actuator combination, single action is action type
amplifier is easy to transform into a reaction type amplifier (input signal increases, the output pressure decreases).
Air pressure0.14-0.7MPa(140-700KPa)
Output pressure0-0.7MPa(0-700KPa)
Air consumptionThe output 50% air pressure gas consumption.
Single acting type:  5NI/min at 140KPa air supply
Double acting type:  15NI/min at 400KPa air supply
The biggest processing capacityWhen the output side air vent
Single acting type：175NI/min at 140KPa air supply
Double acting type：400NI/min at 400KPa air supply
