Product Description

Summary
The JF120 pneumatic valve positioner is a device that receives a pressure signal ranging from 3 to 15 PSi from a pneumatic controller or control system and, by actuating a pneumatic actuator, controls the valve position.
Features
① Compact structure; ② Easy switching between forward and reverse, as well as between single‑acting and double‑acting modes; ③ For small‑size pneumatic actuators, vibration can be prevented by reducing the restrictor orifice in the positioner; ④ Low air consumption and excellent cost‑effectiveness; ⑤ No need to replace components—simple adjustments enable split‑range control within a 1/2 range.
