PRESSURE CONTROL
VALVE
The Hydrocore™ Pressure Control Valve (PCV) maintains a constant downstream pressure ‘Pd’ irrespective of changes to the down stream pressure. The pressure control valve setting can be changed multiple times as conditions change and changes are required.
Principles of Operation
The PCV reduces the upstream pressure 'Pu' by a fixed ratio 'R' to a required downstream pressure 'Pd', irrespective of the valve's flow rate. The valve's piston is in equilibrium state when the required pressure reduction ratio exists.
FEATURES
-
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
