How They Work
Installed directly after the water meter in homes, commercial buildings, and manufacturing plants, a water pressure reducing valve automatically reduces the pressure from the water supply main to a lower, more sensible pressure.
There are two types of water pressure reducing valves-- direct acting and pilot operated-- which use globe or angle style bodies. Direct acting valves are the more popular water pressure reducing valves, consisting of globe-type bodies with a spring-loaded, heat-resistant diaphragm connected to the outlet of the valve that acts upon a spring. This spring holds a pre-set tension on the valve seat installed with a pressure equalizing mechanism for precise water pressure control.
