Description

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.

Series DX Knife Gate Valve                                      

•  Elastomer lined                                                                                   
•  100% full port opening
•  Elimination of packing
•  Abrasion resistant sleeves
•  Bubble tight shut-off, bi-directionally
•  Eliminates seat cavity which prevents slurry build-up or dewatering

The Series DX Slurry Knife Gate Valve is recognized as the most durable and user-friendly knife gate valve.  It is designed especially for heavy slurry applications in the power and mining industries.  

 When the Series DX valve opens, the reinforced elastomer sleeves seal against each other and provide a 100% full port opening, minimizing turbulence which in turn minimizes wear.  The seats isolate and protect all metal parts of the valve from coming in contact with the process.  When the valve is closed, the sleeves provide a drop tight seal.  Another unique feature to this valve is its ability to provide drop tight shut-off in both directions.
