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.
