Electric actuated globe control valve

Model:

  • Port size:DN15-DN300
  • Pressure:PN10-PN64 CL150-CL600
  • Medium:Water,steam,oil,etc.
  • Temperature :-29~450℃
  • Body material:WCB,WCC,CF8,CF8M,etc.
  • Description:
  • Electric actuated globe control valve Feature

    Electric actuated globe control valve is non-balanced single seated or balanced cage type structure Control Valve. The flow port is S pattern, and the flow-guiding part around the cage can also make the fluid flow smoothly. Therefore, the pressure drop of such Electric actuated globe control valve is very low, the flow capacity is big, and the noise is low. Electric actuated globe control valve is used for pressure,temperature,flow,level control in the industry system.
