Slip-on Flanged Flat Bottom Duckbill Check Valve

Slip-on Flanged Flat Bottom Duckbill Check Valve

The XH installs by slipping over the end of an exposed piece of pipe, and is fastened with compression clamps. The inside diameter of the XH’s cuff is fabricated to exactly match the outside diameter of the pipe.

The original Tideflex design, the XH, has a flare on the top and bottom of the valve. It has been superseded by the XH and has been standardized by many consultants and owners. The patented XH design is a product of 25 years of experience, research and development and testing elastomeric "duckbill" check valves. In addition to the benefits provided by a flat-bottom valve, the XH also benefits from the increased angle of the upper "spine". The inherent geometry and construction of the XH yields a more durable check valve with greater strength to support not only the weight of the valve itself, but the weight of the water discharging from it. In large diameter valves, this weight can amount to several tons!

The XH can also be installed on the OD of elliptical pipe and many arch pipes.
