- 【Heavy duty brass material】The backflow preventer consists of a brass body, stainless steel working parts, a one-piece strainer and a durable rubber disk. Superior corrosion resistance provides decades of reliable service with a life expectancy 3 times longer compared to standard valves. Precision-machined double check mechanism maintains leak-free performance during frequent pressure surges
- 【Powerful and consistent performance】AQOVOR's Dual Check Valve is suitable for hot or cold water and can be used under continuous pressure. Stable operation over a temperature range of 33°F (freeze-proof) to 210°F (boil water resistant). Maximum operating pressure is 175psi (12.1 bar) - tested to 5000+ pressure cycles. Minimum required pressure is 25 psi (1.7 bar). Fail-safe reliability in extreme temperature and pressure environments
- 【Standard sizes for a wide range of applications】Brass back flow preventer valves with universal 1/2-inch female threaded connections fit seamlessly into standard U.S. piping, eliminating the need for piping modifications. Designed for smaller supply lines, ideal for laboratory equipment, process tanks, sterilizers and dairy applications. Especially recommended for boiler feed lines to ensure return pressure remains above system pressure during operation.
- 【Critical safety note】To avoid water damage during operation of the check valve, a drain must be installed approximately 12 inches above the floor drain. If used on a boiler, do not use air gap fittings on surfaces to prevent personal injury from scalding. Under no circumstances should the exhaust port or discharge line be blocked
- 【User-friendly design】Cast-in ‘INLET’ & ‘VENT’ labels eliminate installation guesswork - no peeling stickers or faint markings. Raised brass lettering is legible for life, ensuring proper orientation and preventing reverse connections from causing leaks. Can be installed vertically or horizontally, providing flexibility in your installation
