Series 37G Inline Check Valve
The revolutionary design of the Series 37G Inline Check Valve provides
superior backflow protection. This unique "duckbill" design eliminates
costly backflow from oceans, rivers, and other waterbodies and piping
systems.
The Series 37G is available in a wide variety of elastomers and is
designed to meet your exact flow specifications.
The cuff of the Series 37G Valve is constructed to have the same outside
diameter as the inside diameter of the mating pipe. This allows the valve
to be inserted into the pipe and held in place by means of an internal
expansion clamp. Tideflex
valves for added security and stability.
The 37G effectively has a zero face-to-face dimension because they
fit completely inside of the pipe. No modification of piping is required
provided adequate pipe length exists.
• Simple Design
• Cost Effective
• No Hinges, Levers or Springs
• Minimal Routine Maintenance
