Description
Titan® Check Valve, Dual Disc Wafer, Series: CV 41-DI, 8 in Nominal, Flanged, 250 psi WOG, 150 lb, 100 deg F, 3-3/4 in Inlet to Outlet Length, Ductile Iron Body, 300 Stainless Steel/Buna-N/Aluminum Bronze Trim, Epoxy Painted, 11 in OD
Features:
- Cost efficient 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: Contour of body provides a short and straight flow path that generates very little turbulence
- 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 discs that close near zero flow velocity
- The lightweight, split disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum
- 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
- Versatile design: Sizes 2 in through 6 in are designed to fit bolt circle patterns for both cast iron ANSI classes 125/300 and ductile iron ANSI classes 150/300
- Resilient soft seats (EPDM, FKM or Buna-N) ensure a bubble tight seal that meets or exceeds API 598 test requirements
Applications:
For liquids and gases where flow reversal can cause surge and water hammer
