Pneumatic heating jacket control valve is composed of pneumatic actuator, valve body, spool, thermal insulation jacket and other parts. The pneumatic actuator receives external pneumatic or electrical signals, drives the valve spool to make linear motion in the valve body, changes the flow area between the valve spool and the valve seat, and regulates the medium in the pipeline. At the same time, the insulation jacket keeps the temperature of the medium in the pipeline constant through heating methods such as electric heating elements or steam.
