SS 321 Tilting Disc Check Valve, ASME B16.34, 6 IN, CL2500

Product Name: SS 321 Y Type Tilting Disc Check Valve
Design Standard: ASME B16.34
Body Material: Stainless Steel SS 321
Size: 6 Inch, DN150
Pressure: Class 2500 LB, PN420
End Connection: BW End

The tilting disc check valve features a pivot point at the center of its disc, addressing the limitations of traditional swing check valves. Unlike the swing type, which requires higher flow velocities to keep the disc open and maintain higher cracking pressure, the tilting disc check valve can remain fully open and stable at lower flow rates. This results in a significantly lower pressure drop in low-pressure situations compared to the swing type. However, at higher flow rates, the tilting disc check valve experiences a higher pressure drop than the swing type.
