Watts Water Technologies M2 Pressure Reducing Valve

Description:

The Watts M2 Pressure Valve 1-1/4" (SS5) is a water pressure reducing valve designed to automatically reduce and regulate incoming water pressure to a controlled downstream level. With an adjustable pressure range of 25–75 PSI, it helps protect plumbing systems, piping, fixtures, and equipment from excessive supply pressure while maintaining consistent operating conditions. It is commonly installed in commercial buildings, industrial facilities, municipal water systems, and large residential applications requiring dependable pressure regulation.

Applications:

The Watts M2 Pressure Valve is widely used in potable water distribution systems, commercial plumbing installations, industrial process water systems, apartment buildings, schools, hospitals, irrigation systems, and manufacturing facilities. By maintaining stable downstream pressure despite fluctuations in supply pressure, it helps reduce water waste, minimize water hammer, extend equipment life, and improve overall system reliability. It is suitable for installations where adjustable pressure regulation between 25 and 75 PSI is required.
