4 In Cast Iron Double Check Valve Backflow Preventer Assembly with NRS Shutoff Valves, Epoxy Coated Using ArmorTek Technology
This 4 inch double check valve backflow preventer assembly is designed to prevent the reverse flow of contaminated 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. It is ideal for protection at cross-connections identified as non-health hazard applications and from other contaminants found at the service line entrance. This assembly consists of an epoxy coated cast iron body, non-rising stem resilient seated gate valves, test cocks, and a modular check design for easy maintenance with center stem guide. The captured spring is accessible through a bolted cover plate. The coating on this backflow assembly uses ArmorTek(R), a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
Features
- Utilizes advanced ArmorTek coating technology to resist corrosion of internals
- Cast iron body construction with patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion
- Replaceable bronze seats
- Maximum flow at low pressure drop
- No special tools required for servicing
