Description
Titan® Swing Check Valve, Single Disc Wafer, Series: CV31-DI, 3 in Nominal, Wafer End Style, 250 psi WOG Pressure, 150 lb Pressure Class, 100 deg F, No Low Lead Compliance, 2.62 in Inlet to Outlet Length, Ductile Iron Body, 316 Stainless Steel Trim, Buna-N Softgoods, 5-1/4 in Dia
Features:
- 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
