1.  Fits inside pipe I.D.  Fastened with internal expansion clamp.  Features all-elastomer, maintenance-free design.  Is custom-built to customer specifications.  Closes on entrapped solids. Materials of Construction  Valves are available in pure gum rubber , neoprene, Hypalon ® , buna-N, Viton ® and EPDM.  Stainless steel expansion clamps. Series 37G The Series 37G InLine Check Valve was developed specifically for installations where clearance below the invert of a pipe is insuf- ficient to clear the flange of the standard Series 37. The 37G effectively has a zero face-to-face dimension since it can be com- pletely slipped into an existing pipe. Piping modifications are not required to provide space for the valve. The Series 37G design uses the slip-on principle in reverse. A special clamp that expands outward is pro- vided to secure the valve to the inside of a pipe, enabling the valve to be installed easily on the outlet pipe from a manhole, such as in a CSO system. The pressure drop of the Series 37G is increased because of the smaller I.D. required to fit the check valve in the line. Tideflex ® Technologies recommends the valves be pinned to the pipe. Each clamp has four pre-drilled holes to allow installa- tion of anchors/bolts. Contact our engineer- ing staff for additional information.
