Model LFCS check stop valves are designed for use at the hot and
cold water inlet sup plies for mixing and tem per ing valves. Model
LFCS valves perform triple duty as: 1) iso la tion valves,
2) check valves, and 3) strain ers. The union con nec tions
facilitate service and main te nance of both the valve and the
strainer.
Model LFCS valve protects against cross flow of hot and cold
water in the system and provide isolation of the mixing or
tem per ing valve during ser vic ing and main te nance of the valve
and strain er. The integral fine strainer protects the valve from
dam ag ing dirt and other debris.The Model LFCS valve features
Lead Free* construction to comply with Lead Free* installation
requirements.
