  • Description:
  • Pneumatic steam jacketed control valve Feature

    Pneumatic steam jacketed control valve mainly applied to the occasions of thermal insulation,full the heat medium into the gap between valve body and metal jacket to keep thermal insulation and prevent fluid crystallization occurs, as well as the increase of viscosity, which due to the temperature reduction.

    Pneumatic steam jacketed control valve muti-springs pneumatic reinforce actuator makes the control valve realize the conversion of normal close and normal open on site easily,the spring can be effectively protected from the corrosion to prolong the service life of  control valve actuator and convenient for customers operation. The actuator of Pneumatic steam jacketed control valve and the intelligent control valve positioner are connected pipeless to strengthen the antisemitic performance,stability and precision adjustment, to meet to exactly control of the working conditions.
