The Backflow Direct Deringer 20 Double Check Valve Assembly is designed to prevent non‐health hazard pollutants from entering the potable water supply system caused by backpressure and/or siphonage conditions.
The Backflow Direct Deringer 20 Double Check Valve uses two independent Dual Action Check modules and two integral resiliently seated shut‐off valves all of which are contained within a single rigid valve housing constructed entirely of 304 stainless steel. Both integral shutoff valves include pre‐wired supervisory tamper switches contained within a weatherproof actuator housing approved for both indoor and outdoor use. Dual action check modules operate as a "poppet style" check under low flow conditions, operate as a "swing style" check under high flow conditions and use replaceable silicone elastomer sealing discs. Assembly test cocks are handle‐less and operate via a tamper resistant actuator. The valve has a single full access service port and cover with an "inline" replaceable elastomer seal, and is serviceable without special tools. It is approved for both horizontal and vertical applications.
