RPLF4A Reduced Pressure Backflow Preventer, 3 in, Flange, 304/304L Stainless Steel

The Apollo™ MODEL RPLF 4A 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 backsiphonage. 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.
