    Patented by Red Valve Company, the CheckMate® Inline Check Valve is ideal for backflow prevention and odor mitigation. In outfalls, stormwater, CSO and SSO applications, the CheckMate's® custom-engineered, all-rubber unibody design eliminates costly backflow from oceans, rivers and interceptors. CheckMate® Valves are readily available in 4" to 72" sizes. The CheckMate® is built to suit all your site specific and flow needs.

    The CheckMate's® unique elastomer-reinforced design provides a proven record of maintenance-free performance, cost savings and results that no other inline check valve can match. The valve has a 100% fabric and elastomer construction that eliminates corrosion problems. Because the CheckMate® is made with a unibody construction, there are no mechanical components to catch debris, corrode or fail.  The result is in savings - both in time and costs.
