3 way globe type control valve

3 way globe type control valve Product introduction

　China 3 way globe type control valve manufacturer, factory and supplier. 3 way globe type control valve has diverging and converging structure, 3 way globe type control valve adopts double valve cores up and down guide structure, equipped with multiple spring actuator. 3 way globe type control valve can replace two sets two-way valve and widely used in many occasions to regulate pressure, flow rate, temperature and liquid level.

3 way globe type 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. 3 way globe type 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, 3 way globe type control valve can bear high pressure difference, easy for connection.
4.While with low nominal size and pressure difference, converging control valve can be used in diverging occasion. However, while nominal size higher than DN100 and high pressure difference, converging control valve and diverging control valve can’t be exchanged.
