Electric diverging 3-way control valve

Model:

  • Port size:DN20~300, NPS 3/4〞~ 12〞
  • Pressure:PN16 ~ 100,150LB ~ 600LB
  • Medium:Water,oil,steam,gas
  • Temperature :-196~450℃
  • Body material:WCB LCB CF8 CF3 CF8M CF3M
  • Description:
  • Electric diverging 3-way control valve feature

    Electric diverging 3-way control valve is diverging structure and has converging and diverging structure for choice,electric diverging 3-way control valve adopts double valve cores up and down guide structure, equipped with multiple spring actuator. Electric 3-way control valve can replace two sets two-way valve and widely used in many occasions to regulate pressure, flow rate, temperature and liquid level.
    The Electric diverging 3-way 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.Electric diverging 3-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, Electric diverging 3-way 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.
