Swing check closure is affected by gravity (weight of disc) and reverse flow. The pivot point of the
swing check valve is outside the periphery of the disc and the greater the head, the greater the
possibility that the fluid will flow back through the valve before the disc can be shut-off.

To effect complete shut off, disc of a swing check valve must travel through a 70° to 90° arc to the valve seat. Without resistance to slow the disc’s downward thrust and reverse flow, the shut-off can result in slamming and damaging water hammer.
