Mini Water Pressure Reducing Valves**
Sizes: 1⁄8", 1⁄4" & 3⁄4" Male x 3⁄4" Female
(3, 8 & 20 x 20mm) Hose Connection
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 con­sumption. This series is ideal where a small economical package is required such as on special industrial process applications, miscel­laneous 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.

Specifications
A Mini Water Pressure Reducing Valve shall be installed where indicated on the plans. Lead Free* Mini Water Pressure Reducing Valves shall be constructed using Lead Free* materials. Lead Free valves shall comply with state codes and standards, where applicable, requiring reduced lead content. Valve shall have a Lead Free* brass body and stainless steel stem and spring. Valve shall come standard with a Series LF560 (threaded), LFH560 (hose connection).
*The wetted surface of this product contacted by consumable water contains less than 0.25% of lead by weight.
** A water saving test program concluded that reducing the
supply pressure from 80 – 50psi (551 – 346 kPa) resulted in a water savings of 30%.
