WATTS Water Pressure Reducing Valves

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

Working Mechanism

• The direct acting type valves have internal spring loaded diaphragm which connects to a disc that modulates outlet flow controlling pressure.
• High pressure water that enters the valve is constricted inside the valve body.
• This constricting action is controlled by a disc and an adjustable spring loaded diaphragm.
• Even if the input supply pressure fluctuates, this diaphragm & disc combination ensures a constant water flow at the outlet.
• The spring tension controls the outlet water pressure which can be increased / decreased by loading or unloading the valve spring.
• In case the downstream water pressure is above the set pressure, the diaphragm inside the valve compresses the spring.
• If the downstream water pressure is under the set pressure, the valve spring pushes the valve to increase the flow from the regulator.
• These valves are installed mid line before fixtures and after backflow preventers and water supply stops. They have inlet and outlet ports that are installed in series with the pipe.
