LEVEL CONTROL VALVE

The Hydrocore™ Level Control Valve controls the water level by opening or closing the valve on low or high level conditions in the reservoir. The valve can be actuated by the line-fluid pressure or alternatively by compressed air, hydraulically or electrically.

FEATURES
PRESSURE REDUCING VALVE - CUT.png
  • Accurate, stable & smooth control of pressure and flow regulation.

  • Can suit all valve sizes and pressure ratings.

  • Suitable for low flow (high velocity).

  • Reduces noise and vibration.

  • Improved anti-cavitation on valve seat area.

  • Increased longevity of valve lifespan.

  • Requires minimal maintenance, consisting of an annual cleaning and greasing of the sealing surfaces inside the valve’s bore. 

  • Various types of directional valves, operated by various types of actuators, could be applied for the purpose of venting or pressurizing of the control compartment.

  • Stainless steel moving internals parts

  • Cast steel body 

  • Low pressure drop across valve

  • Flanges and face-to-face dimensions to customer specification
