Product Description

Summary
The JF400 series electric valve positioners are designed for use with pneumatic actuators. They convert a 4–20 mA DC input signal into an output air pressure to control the actuator’s movement. At the same time, they provide feedback based on the actuator’s stroke, enabling precise positioning in response to the control signal.
Features
① Suitable for both small- and large-capacity actuators; ② Low air consumption; ③ Optional output characteristics; ④ By simply replacing the cam assembly, it is possible to switch between linear and angular stroke configurations.
