The Hydrocore™ Pressure Reducing Valve accurately maintain a set ratio between the upstream and downstream pressures, irrespective of the valve's flow rate. The valve's piston is in equilibrium state when the required pressure reduction ratio exists.
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
