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.

Tideflex Curved Bill Technology

Red Valve Company has been committed to the advancement of the Tideflex Check Valve through on-going research and development since its inception in late 1970’s. The latest advancement is the incorporation of a curved bill the valve that improves the sealing capabilities of the valve with entrapped solids.

Wide-Bill Tideflex Diffuser Valves (Series WB)

TFD Wide Bill Design

TFD units for Multi-port Outfall Diffuser

 

After years of R&D and development of innovative fabrication equipment, Red Valve introduced Wide-bill Tideflex Diffuser Valves (Series WB). Series WB’s open up to and beyond the nominal port/riser diameter which means the headloss at peak flow is the same or less than the exit loss of the fixed-diameter port. No longer is there a need to size Tideflex Diffusers larger than the nominal port/riser size. As with all Tideflex Diffusers, the Series WB’s are inherently a variable orifice so the jet velocity is enhanced at all flows below peak flow.
