1.6 Style 790: ProFlex Low Head Loss In-Line Rubber Check Valve
This type of rubber check valve is designed to slip directly inside of an existing pipe with the supplied stainless-steel expandable
clamp or retaining ring to secure in place; it can be fastened from either the inlet or discharge end of the valve. The standard
Style 790 valve must be installed in a truly round pipe. Out of round pipe may cause distortion of the valve causing valve
failure.
