Product Description
Designed to protect against backflow from a cross-connection of non-health hazard pollutant. Within the assembly are two mechanically independent, spring-loaded poppet type check valves set in an integral cast bronze body. Both check valves are designed at an inclined angle upward from the horizontal centerline of the assembly, and all test cocks are mounted at the top to assure easy access during repair and maintenance when unit is installed in a pit or tight places. Top access for testing, repair and maintenance Corrosion resistant Low head loss Interchangeable poppets and springs Replaceable seats Comes standard with Apollo?� full port ball valves with stainless steel handles Maximum working pressure 175 psig Temperature range 33??F-180??F
Operation
During normal flow conditions, the two check valves are held off their seats, supplying water downstream. Each check valve is designed to maintain a minimum of 1 psi across the valve during normal operation. Should the downstream pressure increase to within 1 psi of supply pressure, both check valves will close to prevent a backflow condition.
The Series 40-100 Top Entry is approved under ASSE 1015, AWWA C-510, CSA B64.5 and USC's FCCC&HR. Contact local water authorities for installation/service requirements.
