Apollo Valves 4ALF21002 Reduced Pressure Backflow Preventer With Y-Strainer

The Apollo® valves model RPLF4A lead-free reduced pressure principle backflow preventers consist of two independently acting, TriForce™ center stem guided check valves with a differential pressure relief valve located between the check valves. The unit is designed to give maximum protection against backflow of health or non-health hazard fluids by either back pressure or back siphonage. The durable domestic stainless steel units (2-1/2 to 8 in) and the FDA epoxy-coated ductile iron units (10 and 12 in) are easily maintained in the line without any special tools. The TriForce™ check valves operate with a spring assist in the flowing condition to provide excellent flow rates which are documented by an independent laboratory.
