The DR300-150A pressure reducing valve protects downstream equipment and pipework against excessive water pressure. This pilot-operated pressure reducing valve is ideal for applications where direct-acting valves do not provide sufficient flow capacity. Its compact design also allows installation in confined spaces.

Installing a pressure reducing valve prevents damage caused by high pressure and reduces water consumption. The outlet pressure remains constant even when the inlet pressure fluctuates, which minimises noise in the system.
