Pneumatic Control Valve
Stainless Steel Pneumatic 3 Way Mixing/Diverting Regulating Valve
stainless steel pneumatic 3 way mixing/diverting regulating valve
Pneumatic 3 way mixing regulating/control valve body has the features as below:
2.Pneumatic 3 way mixing regulating valve can be used for various working conditions, especially for the temperature control system of oil industry heat exchange and automatic control of other industries.
3.Spool structure with side guiding, well stability, no vibration, low noisy, Pneumatic 3 way mixing regulating valve can bear high pressure difference, easy for connection.
4.While with low nominal size and pressure difference, 3 way mixing regulating valve can be used in diverting occasion. However, while nominal size higher than DN100 and high pressure difference, Pneumatic 3 way mixting regulating valve and Pneumatic 3 way diverting regulating valve can’t be exchanged.
