Pressure Reducing Valves are designed to reduce incoming water or steam pressure to a safer constant predetermined downstream level. Depending on the type of valve, the downstream pressure is established by a pressure adjustment setting on the valve or by an external sensor.
Installed directly after the water meter in homes 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.
Twice as much water flows through a system at 150psi pressure than at 50psi. Much of this additional water is wasted and not needed for normal usage.
If less water flows through the system, less energy is needed to heat domestic hot water. Calculations show that pressure reducing valves can save as much as 30% on domestic water heating costs.
When the community's wastewater treatment load is reduced, cost benefits accrue to both the environment and your bottom line. Many municipalities prorate sewer usage fees based upon the water meter reading.
Water Pressure Reducing Valves are used in residential, commercial, and institutional applications to reduce incoming water pressure to a lower predetermined level, thereby protecting downstream plumbing system components and reducing water consumption.
Steam pressure reducing valves are used in commercial, industrial, and institutional applications to regulate steam pressure. Used in applications such as oil lines, testing fixtures, autoclaves, steam tables/irons, single radiators, and vulcanizers.
