FDV-R-PN2
The FDV-R-PN2 Pressure reducing valve is an automatic hydraulic control valve, designed to operate in fixed fire protection system ad in peripheral FP water supply systems.
The FDV-R-PN2 pilot controlled hydraulic valve is activated by line pressure. The pilot valve has a spring-loaded membrane which is sensitive to the downstream pressure. The pilot’s spring is pre-set to a desired reduced pressure. Accordingly, it maintains a constant downstream pressure by gradually opening or closing of the main valve, reducing the inlet water pressure to a pre-set desired outlet pressure. As a result, the outlet pressure is maintained constant, regardless of fluctuations in flow rate and changes in main pipeline pressure.
Designed for vertical, horizontal and angled installation, the line pressure operated FDV-R-PN2 Pressure reducing valve features a direct elastomeric diaphragm seal, with no balancing spring or internal metallic wet components in the valve body. In addition, the hydrodynamic pattern design ensures high flow rates with minimum head loss.
