Use of axial flow check valves

Axial flow check valves cannot be supported by flow rate pressure in a large open position and remain in a stable open position. Swing check valves may continue to oscillate with the disc and associated moving parts. To avoid premature wear, noise or oscillating or oscillating operation of moving parts, the size of the check valve should be chosen according to fluid conditions. Check valve companies can support the check valve in open, safe conditions, the earliest fluid speed required is called the minimum velocity.
The axial flow check valve has a lower V value than the swing and oblique disc check valve. When the check valve is installed to the full open position, it is only the component of the total flow velocity pressure supporting the disc in the full open position. Pressure loss can be minimized and stroke reduced. Swing check valves maintain the same VC value. If the nominal flow rate passes through the check valve to or beyond the device's check valve, it can be seen that having a smaller V can greatly reduce the protection cost of adding the reliability of the check valve.
