Check Valves are automatic shut-off valves that are commonly used for preventing backflow or drainage in a piping system. Often applied on the discharge side of pumps, check valves prevent the system from draining if the pump stops and protect against backflow, which could harm the pump or other equipment.

- Economical design - Low weight and short laying length produce savings in initial cost, space requirements and installation when compared to full body, swing type check valves
- Minimal head loss - Head loss is minimized by providing a short, straight and virtually unobstructed flow path
- Additionally, the spring loaded disc is designed with very low cracking pressure which reduces the amount of energy required to open the valve
- Quick closure to reduce water hammer - Shut-off is achieved via the fully automatic, spring assisted disc that closes near zero flow velocity
- The lightweight, single disc design creates a positive shut-off prior to flow reversal which helps to keep surges to a minimum
- Durable, high quality design - The CV31's ductile iron body maintains the anti-corrosive properties of cast iron while achieving a yield strength comparable to carbon steel
- Ductile iron also offers higher pressure/temperature ratings than cast iron in the same pressure class
- Resilient soft seats - Field replaceable, Resilient soft seats (Buna-N O-ring) coupled with precision machined sealing surfaces help to ensure a bubble tight seal that meets or exceeds API 598 test requirements
- Buna-N O-ring
