Pneumatic 3 way mixing control valve is mixting structure to combine two-way flowing fluid  into one-way fluid ,penumatic 3 way control valve has diverting and mixing structure,Pneumatic 3 way mixing controlling valve adopts double valve cores up and lower guide structure, outfitted with multiple spring actuator.Pneumatic 3 way mixing controlling valve can replace two sets two-way valve and broadly utilized in many occasions to manage pressure, flow rate, temperature and liquid level.

ZMAQ Pneumatic 3 way mixing regulating/control valve body has the features as below:

1.compact structure, light weight, sensitive action, low pressure drop loss, new high allowable pressure, large valve capacity, accurate flow characteristics and convenient maintenance, etc.,
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.
