ProFlex - Proco Style 720 - Rubber Check Valve

The PROCO Series 700 “ProFlexTM” Check valves are offered as direct replacements for ineffective and maintenance ridden flap type check valves, commonly known to seize, rust and bind in unwanted positions. Unlike flap type valves, the “ProFlexTM” rubber check valve will handle large obstructions without jamming or having swing gates binding open. Specify the PROCO Series 700 “ProFlexTM” rubber check valves to provide backflow protection from (1) Sewage slurries, (2) Outfalls to ocean fronts from heavy rainfall activity, (3) Prevention from land erosion due to back flow conditions, (4) Protection from saltwater to fresh water ponds and catch basins and numerous other water based applications. Our history in the manufacture of rubber piping products dates back to 1930. When an engineered solution is needed to solve a piping or backflow problem, call PROCO.

The PROCO Series 700 “ProFlexTM” Rubber Check Valve are available in a Flanged (Style 710 or 720), Sleeved (Style 730 or 740), or Jacketed (Style 750). Inline orifice (style 770/780)

Style 720: Flanged Inline:
Designed to fit directly inside of an existing pipe.
