  • Pressure Reducing Valves

    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.

    Every Drop Counts - Why Install a Pressure Reducing Valve?


    Water Savings

    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.


    Energy Savings

    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.


    Wastewater Savings

    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.

    Types of Pressure Reducing Valves


    Water Pressure Reducing Valves

    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

    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.

    Let me just say that the pictured item isn''t what I received. I was replacing a N35B which is obsolete and made of all BRASS. I received an N45B which is what I ordered, but the entire top part is made of PLASTIC. It installed easy enough, but when I was turning the bolt to open the valve allowing pressure, the plastic washer inside broke immediately. I was a little more than half way open when this happened. What I ended up doing was taking apart my N35B and CLEANING IT OUT and put it back on. It is working for now, but I need to find a suitable replacement. Plastic is cheaper not better. I will be returning this item.

    This is a perfect replacement for the original Watts water pressure regulator that was installed when my house was. built 17 years ago. Even though this is an updated model they kept the dimensions virtually the same so it''s basically plug-and-play. Essentially a 15 minute change out with a couple of wrenches and Teflon tape. My cheap water pressure gauge confirms that it holds pressures within two PSI under virtually all load conditions. So I''m pleased
