Manufacturer for Pneumatic Control Valve Having Electro Pneumatic Valve Positioner - Pneumatic three way control valve – Hoyee Detail:

Technical specification

1.Pneumatic steam three way control valve is 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 steam three way control 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 steam three way control valve can bear high pressure difference, easy for connection.
4.While with low nominal size and pressure difference,Pneumatic steam three way control valve can be used in diverting occasion. However, while nominal size higher than DN100 and high pressure difference,mixting control valve and divertinging control valve can’t be exchanged.
