TOP ENTRY DOUBLE CHECK VALVE ASSEMBLYThe Apollo MODEL DC4A Double Check Valves are designed to prevent contamination of thepotable water supply due to back-siphonage or backpressure from substances that are objectionable, but non-health hazards. The modular check valve cptured spring cartridges havereplaceable seats and reversible silicone seat discs. Apollo ball valve shut-offs with stainlesssteel handles and nuts are standard.

OPERATIONDuring normal flow conditions, the two check valves are held off their seats, supplying waterdownstream. 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.

Double Check ValveBackflow Preventers

TOP ENTRY DOUBLE CHECK VALVE ASSEMBLYThe Apollo DC-40 Series Top Entry Double Check Valve Assembly is designed to protect against backflow from a cross-connection of non-health hazard pollutant. Within theassembly 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 easyaccess during repair and maintenance when unit is installed in a pit or tight places.

OPERATIONDuring normal flow conditions, the two poppet check valves are held off their seats, supplyingwater downstream. Each check valve is designed to maintain a minimum of 1 psi across thevalve during normal operation. Should the downstream pressure increase to within 1 psi ofsupply pressure, both check valves will close to prevent a backflow condition.

DCDA-4A Series

Sizes 2-1/2"-12

DCDA-4A DOUBLE CHECK DETECTOR ASSEMBLYThe Apollo MODEL DCDA-4A Double Check Detector Assembly is 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 TriForce center stem guided check valves feature replaceable and reversible silicone seat discs. The by-pass assemblyserves to measure accurate water use of up to 2 GPM. Available in a wide variety of shut-offoptions.

The Type 2 bypass uses the first check of the mainline assembly as the first check of the bypass.The second check of the bypass is a single check valve with a model number and serial numberfor test recording. This arrangement is approved by the Tenth Edition of the USC FCC&HRManual of Cross Connection Control as well as ASSE. The arrangement provides the same levelof protection as the original (still optional) Type 1 bypass and the testing procedure is the same.

DC-4S Series (Previously Model DC)TOP ENTRY DOUBLE CHECK VALVE ASSEMBLYThe Apollo DC-4S Top Entry Double Check Valve Backflow Preventer is designed to preventbackflow by either back-pressure or back-siphonage from a cross-connection between potablewater lines and substances that are objectionable, but not a health hazard. It is an economicaldevice that is easily repaired in the line. The device consists of two independently acting, spring-loaded poppet type cartridge check valves in an integral cast bronze body. Four test cocks andtwo shut-off valves which are quarter-turn, full-port, resilient-seated and ball type complete theassembly.

OPERATIONDuring normal flow conditions, the two check valves are held off their seats, supplying water down-stream. Each check valve is designed to maintain a minimum of 1 psid across the valve during normal operation. If at any time the pressure downstream of the device increases to within 1 psi ofsupply pressure, both check valves will close to prevent a backflow condition from occurring.

FEATURES Corrosion resistant Easy to install, repair and maintain Low head loss Replaceable check cartridge modules Comes standard with Apollo full-port

n AND Z FLOW REDUCED PRESSURE PRINCIPLEThe Apollo Series RP-40 Reduced Pressure Principle Backflow Preventer is designed to givemaximum protection against backflow caused by either back-pressure or back-siphonage. Thedurable, but economical, device is easily maintained in the line without any special tools. It consists of two independently acting spring-loaded poppet check valves with an automatic differential relief valve located between the check valves. The diaphragm and the sensing passage are built into the all bronze body to eliminate possible damage. The assembly offersinstallation flexibility by providing inlet and outlet bronze elbows to meet space requirements,adaptability and lower installation cost. The No. 3 and No. 4 test cocks are mounted at the top toassure easy access during repair and maintenance when unit is installed in tight places.

OPERATIONDuring normal flow conditions, the two check valves are held off their seats, supplying water down-stream. The relief valve is held shut by supply pressure acting through the internal sensing passage,on the relief valve diaphragm. In the area between the check valves, called the zone, the pressure ismaintained at approximately 7 psi lower than supply pressure. Should a back-pressure or back-siphonage condition occur, the second check valve will seal, prohibiting the backflow of water. Shouldthe second check valve become fouled, the pressure in the zone will increase causing the differentialrelief valve to open to atmosphere. This will maintain the pressure in the zone at least 2 psi lowerthan supply pressure.

RPDA-4A Series

RPDA-4A REDUCED PRESSURE DETECTOR ASSEMBLYThe Apollo MODEL RPDA-4A Reduced Pressure Detector Assembly consists of two independ-ently acting, TriForce center stem guided check valves with a differential pressure relief valvelocated between the check valves. The unit is designed to give maximum protection againstbackflow of health or non-health hazard fluids by either back-pressure or back-siphonage andat the same time detect leakage or unauthorized use of water from fire or automatic sprinklersystems. The durable stainless steel units (2-1/2 to 8) and the FDA epoxy coated ductile ironunits (10 and 12) are easily maintained in line without any special tools. The TriForcecheck valves operate with a spring assist in the flowing condition to provide low flow rateswhich are documented by ASSA or USC FCCC&HR approval curves.

The Type 2 bypass uses the first check of the mainline assembly as the first check of thebypass. The second check of the bypass is a single check valve with a model number andserial number for test recording. This arrangement is approved by the Tenth Edition of theUSC FCC&HR Manual of Cross Connection Control as well as ASSE. The arrangement pro-vides the same level of protection as the original (still optional) Type 1 bypass and the testingprocedure is the same.

REDUCED PRESSURE PRINCIPLEThe Apollo Series 40-RP Reduced Pressure Backflow Preventer consists of two independently acting, spring-loaded center stem guided check valves with a differential pressure relief valve located between the check valves. The all bronze relief valve module iseasily removed from the ductile iron check valve body. Pressure sensing passages are builtinto the bronze relief valve module to prevent possible damage from mishandling or vandalism. The unit is available with inlet and outlet shutoff valves. Four test cocks, three onthe backflow preventer valve body and one on the inlet shutoff valve, complete the assembly.

The Type II bypass uses the first check of the mainline assembly as the first check of thebypass. The second check of the bypass is a single check valve with a model numberand serial number for test recording. This arrangement is approved by the Tenth Editionof the USC FCC&HR Manual of Cross Connection Control as well as ASSE. Thearrangement provides the same level of protection as the original (still optional) Type Ibypass and the testing procedure is the same.

The mainline unit consists of two independent spring-loaded, poppet type check valveassemblies with a diaphragm actuated and spring-loaded, relief valve assembly located betweencheck valves. Two resilient wedge gate valves and four test cocks complete the mainline unit. Theby-pass consists of an approved reduced pressure assembly, four test cocks, two shut-off valvesand a water meter.

OPERATIONDuring no flow conditions, the mainline and by-pass check valves will remain closed. Also, bothmainline and by-pass relief valves stay closed due to the pressure differential between supply andzone pressure. If there is a low flow demand (up to a minimum of 3 gpm) of water downstream,which may be caused by a system leak or unauthorized use, the flow is routed through the watermeter to monitor such consumption. Higher flow will tend to open the mainline check valves atwhich point water continues to flow at the by-pass at a rate below capacity. In the event pressureincreases downstream, tending to reverse direction of flow, both check valves in the mainline andby-pass are closed to prevent backflow. If the second check valve in either the mainline or by-passis prevented from closing tightly, leakage into the reduced pressure zone increases pressure andwill cause the relief valves to open. If the supply pressure
