Features & Benefits

Full Port Check Valves offer some impressive advantages over other types of check valves.

  • Low Pressure Drop (High Cv) Our elastomer hinge check valves have larger open area than other designs, thus providing higher capacity and lower pressure drops than swing and lift check, or even traditional dual plate wafer designs.

  • USA Content When specified, valves can be manufactured to meet stringent 75% or higher USA raw material content requirements.

  • ARRA Compliant USA content, substantial transformation and local assembly makes our Full Port Check Valves ARRA compliant for government funded projects.

  • Alleviates Water Hammer When spring activated, our discs are designed to close 33% faster than standard dual disc check valves due to the fact that they are closed at a 30 degree angle. This makes for an effective non-slam design when installed in liquid applications.

  • Simple Installation Available in a variety of connection types including Male NPT, Female NPT, Grooved End and Plain End. Grooved End valves are suitable for use with Victaulic® couplings. Plain End valves are suitable for TIG welding or for use with hose clamps.

  • Variety of Configurations We stock a wide variety of valve bodies in different styles and materials. These can be assembled with any one of our standard disc, optional spring and elastomer seal choices to make a valve that exactly fits your application. Pins and hardware are always 316SS. Custom lengths are available.

  • Our patented, aerodynamic wing support and reinforced elastomer hinged double discs provide the lowest resistance to flow. Front and rear disc plates provide strength and stability and ensure positive seating. Optional springs are available in a variety of tensions.
