The tilting disc check valve features a pivot point at its center, designed to address the limitations of traditional swing check valves. Unlike swing check valves, which require high fluid velocity to remain fully open, tilting disc check valves can stay open and stable even at lower flow rates. This allows for improved performance in low-pressure applications, as they require lower cracking pressure and exhibit minimal pressure drop.
However, at higher flow rates, the tilting disc check valve experiences a higher pressure drop compared to the swing check valve. This makes it a suitable choice for applications where stable operation at low flow rates and reduced pressure loss in low-pressure conditions are critical.
