Series LF560, LFH560 Mini Water Pressure Reducing Valves are
designed to reduce incoming water pressure to a sensible level
to protect plumbing system components and reduce water con-
sumption. This series is ideal where a small economical package is
required such as on special industrial process applications, miscel-
laneous plumbing applications and OEM equipment. Series LF560
and LFH560 are suitable for water supply pressures up to 300psi
(21 bar). The LF560, LFH560 features Lead Free* construction to
comply with Lead Free* installation requirements.
Features
