4 IN SS Reduced Pressure Zone Assembly Backflow Preventer, OSY Shutoffs, Short Lay Length
This 4 inch lead free reduced pressure zone assembly backflow preventer helps prevent the reverse flow of fire protection substances and water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and from other contaminants found at the service line entrance. This assembly consists of a short lay length stainless steel body, test cocks, corrosive resistant stainless steel bottom mounted relief valve, torsion spring check valves, and outside stem and yoke resilient seated gate valves.
Features
- Stainless steel body is half the weight of competitive designs reducing installation and shipping costs
- UL and FM outside stem and yoke resilient seated gate valves
- Health hazard application
- No special tools are required for servicing
- Compact construction for smaller enclosures
- Bottom mounted relief valve reduces clearance requirements when installed against an outside wall
- Torsion spring check valves provides maximum flow at low pressure drop
- Short end to end dimensions makes retrofit easy
- Thermoplastic check valves with stainless steel hinge pins for trouble-free operation
