ANSI approved valves used to maintain a preset inlet pressure to prevent damage to the piping systems from excessive water / steam pressure. Intended for both domestic and industrial applications in oil lines, autoclaves and single radiators
Watts water pressure regulator valves reduce incoming water pressure to a safe constant downstream level. They are ideal for irrigation, agricultural, healthcare, production, manufacturing and food & beverage processing applications.

The 152A Series process steam pressure regulators manufactured by Watts are designed to control steam pressure in oil lines, autoclaves, vulcanisers, steam irons and single radiators. These regulators offer highly sensitive responses to reduced pressure changes and maintain fullest possible fluid volume with minimal pressure drop. These pressure reducing valves are capable of bearing supply pressures up to 200 psi. Watts pressure regulators are made of iron and feature a stainless-steel screener, a disc, a stem guide and a sensitivity adjuster to eliminate vibrations caused by critical flow conditions. For different applications, these Watts pressure regulator valves have NPT threaded female inlet and outlet connection ports that can fit into pipes of up to 1-inch diameter.

Yes, water hammer is a phenomenon that generates noise by shocks of high flow water in pipes when the fixture is closed suddenly. The bounce-back caused is called a water hammer. This shortcoming can be reduced by using the pressure reducing valves in piping systems.
Yes, for reducing high water pressures, users can install multiple reducing valves in series or parallel in the line. This cascading effect lowers the water pressure to safer values and protects fixtures.
If the water flow through pipes causes a banging noise, it signifies that the pressure is excessive and needs to be regulated.
Yes, various end fitting configurations facilitate the installation and servicing of these pressure reducing valves. Union fittings of CPVC, solder, female threaded, Quick-Connect, PEX and press end connections and water meter threads can be used for installation.
These two components are most critical in the path of high-pressure water. They handle and regulate excessive water velocity and volatile water conditions in pipings.
Watts water pressure regulator valves protect connected piping and fixtures against blowouts and leakages that are caused by high water pressure. They also maintain the water pressure by regulating the fluctuating water supply at the intake side.
