ASTM A494 CU5MCuC Check Valve, ASME B16.34, 4 Inch, 1500 LB

Product Name: Y Type Tilting Disc Check Valve
Design Standard: ASME B16.34
Body Material: ASTM A494 CU5MCuC, Nickel Alloy
Size: 4 Inch, DN100
Pressure: Class 1500 LB, PN250
End Connection: BW End

The tilting disc check valve is designed with a pivot point at the center of the disc, offering a solution to the drawbacks of traditional swing check valves. Unlike swing check valves that require higher fluid velocity and cracking pressure to remain open, the tilting disc check valve ensures full, stable opening at lower flow rates. This provides a significant advantage in low-pressure systems by reducing pressure drop compared to swing check valves. However, at higher flow rates, the tilting disc check valve may exhibit a slightly higher pressure drop than the swing type.
