CheckMate Inline Check Valve

1 United States Patent # 5,769,125C h e c k M a t e I n l i n e C h e c k V a l v eFlowCheckMate : Your Final Move to Eliminate Backflow! 32 VALVED esigned for Inline ServiceFor an animated demonstration of the CheckMate in operation, please visit: CheckMate Valve in Manhole ApplicationCheckMate Valve in End of Pipe ApplicationBenefits and Features of CheckMate : Extremely Low Headloss No Moving Mechanical Parts to Corrode, Catch Debris or Fail Heavy Duty Elastomer Unibody Construction Quick and Easy Installation Seals Around DebrisDependable Backflow PreventionThe CheckMate Inline Check Valve is the Valve of choicefor both municipal and industrial applications - includingstormwater, wastewater, highway run-off, CSO, SSO andflood control.

2 CheckMate valves prevent unwantedbackflow that can cause surcharging and Inline Check valves have become thespecified solution for residential and commercial areaswhere complete, dependable backflow prevention isnecessary. The CheckMate is not simply a molded it is hand-fabricated, utilizing various natural andsynthetic elastomers and fabric ply reinforcement tocreate a unibody construction. There are no mechanicalparts or fasteners to catch debris, corrode, or fail, makingthe CheckMate maintenance-free. With seven elastomersto select from, the CheckMate can be custom engineeredto resist chemicals, grease and oils typically found instormwater, wastewater and industrial applications.

3 The CheckMate Valve boasts extremely low headloss,allowing for near 100% flow capacity. Its inherent designmakes it the most user-friendly Inline Check Valve on themarket today. From the upstream or downstream end ofthe pipe, simply insert the Valve into position and clampit into place. Typically no modification to the pipe orstructure is required to install the CheckMate . Becausethe CheckMate is recessed inside of the pipe, additionalpermitting is not required. The result is savings in bothinstallation time and operational Valve can successfully withstand severe winter freezes,typhoons, hurricanes and flooding.

4 The CheckMate alsominimizes damage to wetlands, beaches and residentialareas, eliminates hydraulic surges to wastewater treatmentplants and saves municipalities millions of dollars inmaintenance and treatment costs. Operates on Differential Pressure, Totally Passive Virtually No Maintenance Self-draining, 1" of Cracking Pressure silent , Non-slamming Available in Sizes 3" (75 mm) to 78" (1950 mm) Extensive Independent Hydraulic Testing FULLY OPENFlowFULLY 54 VALVED esigned for Inline ServiceCheckMate Applications: Simply Versatile!The CheckMate provides odor and Municipal SewersCheckMate Inline Check valves have become a frequently specifiedsolution for residential and municipal areas where complete,dependable backflow prevention is necessary.

5 The CheckMate Valve smaintenance-free, passive operation provides years of trouble-freeservice. CSO, SSO and OutfallsCheckMate valves are used for interceptor, manhole and outfallpipelines because they maximize pipeline storage and capacity whilepreventing water from backflowing into a sewage treatment plant. TheCheckMate Valve s innovative Inline design allows it to be easilyinstalled without modifications to structures. Stormwater, MS4, Highway Run-off and Site DrainageCheckMate Inline Check valves are the Valve of choice for bothmunicipalities and commercial property owners to prevent costlyflood damage and to maximize system storage.

6 The CheckMate s lowcracking pressure and headloss provide rapid drainage. Flow Equalization Basins, Pump Stationsand Effluent DischargeCheckMate valves provide backflow prevention in between basinsand also protect pumps and capital equipment. The CheckMate s lowheadloss characteristics maximize flow ControlCheckMate Inline Check valves prevent sewer systems offendingodors from escaping, while still allowing water to discharge whenneeded. The CheckMate Valve is designed to eliminate the backflowof unwanted methane and hydrogen sulfide gases that typicallyresult in complaints about odor from the general , Marinas and WetlandsIn low lying areas where headloss is at a premium.

7 CheckMate Valvesefficiently drain with the added benefit of providing absolute " CheckMate Valve replacing a faulty flapgate in a CSO CheckMate is also easily installed by CheckMate installed in a storm sewer drain to stopbackflow from flooding a residential CheckMate is easily installed in a municipal CheckMate s rugged unibody construction prevents CheckMate installed at the Freedom Tower for stormwater Hydraulic TestingCheckMate Inline Check valves are independently testedto determine their hydraulic characteristics in both freeand submerged discharge applications.
