Zurn 34-375XL Zurn 3/4-Inch Lead Free Reduced Pressure Backflow Preventer

Wilkins Reduced Pressure Principle Assy, Lead-Free, Composite Vessel, FNPT x FNPT

Our Zurn 34-375XL reduces backflow up to a Grade of 1. The Wilkins Reduced Pressure Principle Assemblies are used in residential and food service low pressure water systems with a nominal rating of 0.5 to 1.0 inch w.c. These assemblies have brass components, beyond ANSI/NSF Standard 61 requirements, plated with electroless nickel for the lowest possible contact point lea

A large percentage of water supply systems rely on reduced pressure principles to maintain water system integrity. Zurn reduced pressure principle valves use a lead-free Wilkins element with integral metal bellows and patented sealing plates designed to remain clog free for the life of the valve. This design also eliminates the need for an internal backflow preventer (IBFP).

The Wilkins Reduced Pressure Principle (RPP) is an engineered assembly that prevents back flow of water and permits water to flow in only one direction. It is intended for use during pressure and vacuum conditions and protects against negative pressure in downstream piping systems.

The Zurn RPP 3/4-Inch Lead Free Reduced Pressure Backflow Preven­tor for Wilkins Model 40503 is used for the protection of fire pumps and domestic water supplies from entering into potentially hazardous contact with corrosives. It is a composite, line-mounted assembly with a backflow prevention valve that controls fluid flow to or from the protected system.

Zurn compensating-powers are designed to compensate for changes to the differential pressure. The flow can then be calculated using the ideal orifice equation. The advantages of compensating-power reduced-pressure principle assemblies are long-term performance, dependability, and compact design. They are used in applications where constant supply pressure is critical, such as residential service.
