Pressure Reducing Valves

PR - Pressure Reducing Valve
The valve maintains a preset downstream pressure, regardless of upstream pressure or flow rate fluctuation. The main valve is controlled by either a 3-way pilot valve (allowing full opening when downstream pressure drops below theset-point), or by a 2-way pilot valve (creating a pressure differential in any condition).
PR(D) - Proportional Pressure Reducing Valve
The valve maintains a constant pressure ratio between its upstream and downstream pressure, regardless of upstream pressure or flow rate values.
No external control device is needed.
