TITAN FLOW CONTROL 3 in. Ductile Iron Dual Disc Wafer Check Valve w/ Nitrile Rubber Seat & SS Disc - ANSI Class 150 CV41DSB0300

Titan Flow Control CV 41-DI Ductile Iron Dual Disc Wafer Type Check Valve with Nitrile Rubber Seat & SS Disc 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 protects against backflow, which could harm the pump and/or other equipment. 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 discs are designed with very low cracking pressure which reduces the amount of energy required to open the valve Quick Closure to Reduce Water Hammer: Silent shut-off is achieved via the fully automatic, spring assisted disc that closed 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: 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 rating than cast iron Resilient Soft Seats: Resilient soft seats ensure a bubble tight seal that meets or exceeds API 598 test requirements Versatile Design: Sizes 2 - 6 in. utilize a unique scallop design that permits dual pressure service (ASME Class 150 and 300) - Sizes 8 - 12 in. are only rated for ASME Class 150 Specifications Sizes: 2 - 8 in. - Larger sizes available - Please call for more information Type: Wafer - Dual Disc Check Valve ASME Class: 150 (2 - 6 in. sizes provide dual pressure service - Class 150/300) Body: Ductile Iron (ASTM A536) Seat: Nitrile Rubber Disc: Stainless Steel Pressure/Temperature Rating: Class 150 (2 -24 in.): 250 PSI @ 100°F Class 300 (2 -6 in.): 640 PSI @ 100°F Nitrile Rubber Temp.
