The EP4000 series electrical valve positioner is used in conjunction with pneumatic actuators, with an input signal of 4-20mADC converted to output air pressure to control the action of the actuator. At the same time, feedback is provided based on the stroke of the execution structure, so that the stroke of the execution structure can control the signal for precise positioning.
Suitable for small and large-capacity actuators
Low gas consumption
You can choose output characteristics
By replacing the cam mechanism, the conversion between straight and angular travel can be achieved.
