How swing check valve works

The working principle of the swing check valve is somewhat similar to the shut-off valve. The passage of the fluid through the lift check valve is also narrow, so the pressure through the lift check valve is larger than that of the swing check valve, and the swing is started. The flow rate of the check valve is limited.
