ProFlex - Proco Style 770 & 780 - Rubber Check Valve

The PROCO Series 700 “ProFlex” Rubber Check Valve is a cost effective way to control back pressures from sewage treatment plants, outfalls and tidal operations. They are a fully passive flow device requiring neither maintenance nor any outside sources of power or manual assistance to operate.

The PROCO Series 700 “ProFlex” 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 “ProFlex” rubber check valve will handle large obstructions without jamming or having swing gates binding open. Specify the PROCO Series 700 “ProFlex” 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 “ProFlex” 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 770/780:
Designed with a metal or plastic orifice plate and a rubber disk, this valve is an ideal valve to provide high back pressure capability on clean water applications

ELASTOMERS:
All of the PROCO Series 700 “ProFlex” Rubber Check Valves are available in a various selection of elastomers including NSF/ANSI 61 certified material and back pressure capabilities to suit most applications.

The PROCO Series 700 “ProFlex” Rubber Check Valves will not freeze or deform and functions solely on the inlet and back pressure which will be present in each application.

Each valve is carefully constructed using the finest of engineered materials and some of the most experienced rubber technicians in the industry. All check valves are engineered in precise detail to ensure proper operation and will provide years of unhindered operation and trouble free service.
