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.
