Watts LF26A-A Water Pressure Regulating Valve

Description:

The Watts LF26A-A Pressure Regulator (5DMD1) is a 1/2 inch lead-free, two-way water pressure reducing valve designed for small general-purpose applications requiring precise low-pressure control. It automatically reduces and regulates incoming water pressure to a stable downstream pressure, protecting equipment and improving system performance. With the “A” spring range of 1–25 PSI, it is commonly used in beverage dispensing systems, ice machines, humidifiers, drinking fountains, paint spraying equipment, and other light commercial or industrial process applications.

Applications:

The Watts LF26A-A is widely used in beverage dispensers, ice cube machines, humidifiers, laboratory equipment, drinking fountains, paint spraying systems, water treatment equipment, and other small process piping applications requiring accurate low-pressure regulation. Its oversized orifice and forged lead-free brass construction provide reliable pressure control while protecting downstream components from excessive supply pressure. A strainer is recommended upstream to ensure long service life and consistent performance.
