Red Valve Series 39F Check Valve
Overview:
The Series 39F Large-Diameter Slurry Check Valve is designed to handle abrasive slurries, sewage, sludge and other difficult services. The valve’s operation is silent and non-slamming, just like the smaller Series 39.
At the heart of the Series 39F Check Valve is a fabric-reinforced, elastomer check sleeve that provides through flow at minimum pressure drop across the valve at all times. Forward pressure opens the valve automatically and reverse pressure seals the valve. The check sleeve even seals around entrapped solids. This inner elastomer check valve minimizes wear and deterioration caused by continuous operation of abrasive slurries. And there are no mechanical parts such as hinges, disks or metal seats that can freeze, corrode or bind valve operation.
The Series 39F Inline Check Valve is provided with a clean-out ports and flush ports for routine maintenance and cleaning. The valve features an epoxy coated, fabricated-steel body. The valve has thru-drilled flange holes and face-to-face dimensions meet ANSI B16.10 specs. The Series 39F is also available in a plain end x plain end configuration. The Series 39F can also be specially fabricated with offset flanges and a RTF-1 sleeve when bottom clearance is limited (consult factory for special configurations). When ordering, line pressure and back pressure must be provided, as each valve is custom-built to match the flow requirements of the installation.
Description:
The elastomer duckbill Tideflex Check Valve was specifically designed to eliminate operation and maintenance problems associated with flapgate valves – including corrosion, freezing open or shut, warping and clogging. The EPA has tested the Tideflex Check Valve for two years and found that it showed significant improvement over flapgate valves in terms of leakage inflow, debris entrapment, self-cleaning and marine fouling. Today, hundreds of thousands of Tideflex Check Valves are installed and performing reliably worldwide. Tideflex Check Valves have become the world standard for maintenance-free backflow prevention.
Red Valve Tideflex Technologies offers a full line of check valves for backflow prevention and custom-engineered systems for water mixing, aeration and effluent diffusers. Decades of proven field operation, research and development, and continuous engineering enhancements have all combined to make our check valves the most reliable in the industry today.
