DC-4A Series
TOP ENTRY DOUBLE CHECK VALVE ASSEMBLY
OThPe EApRoAlloT MIOODNEL DC4A Double Check Valves are designed to prevent contamination of the
potable water supply due to back-siphonage or backpressure from substances that are
objectionable, but non-health hazards. The modular check valve cptured spring cartridges have
replaceable seats and reversible silicone seat discs. Apollo ball valve shut-offs with stainless
steel handles and nuts are standard.
FEATURES
During normal flow conditions, the two check valves are held off their seats, supplying water
MATERIALS 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.

DC-40 Series
TOP ENTRY DOUBLE CHECK VALVE ASSEMBLY
The Apollo DC-40 Series Top Entry Double Check Valve Assembly is designed to
pOroPteEcRt aAgaTinIsOt bNackflow 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
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.
MATERIALS FEATURES
During normal flow conditions, the two poppet check valves are held off their seats, supplying
water downstream. Each check valve is designed to maintain a minimum of 1 psi across the
Sizes 3/4", 1", 1-1/4", 1-1/2", 2" 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.
