Series 123LP
Water Pressure Reducing Valves
Size: 1⁄2" – 3⁄4" (15 – 20mm)
Series 123LP Water Pressure Reducing Valves are designed to
reduce incoming water pressure to a sensible level to protect
plumbing system components and reduce water consumption.
This series is suitable for water supply pressures up to 200psi
(13.8 bar) and may be adjusted from 10 – 30psi (69 – 207 kPa).
The standard setting is 30psi (207 kPa). All parts are quickly and
easily serviceable without removing the valve from the line.
Features
•  High performance
•  High flow capacity
•  Integral stainless steel valve seat
•  Integral stainless steel strainer
•  Bronze body construction
•  Serviceable in-line
