The in-line spring-actuated lift check also is referred to as the "silent check" because the spring closes the valve before gravity and fluid reversal can slam the valve closed.───由于這種止回閥能夠在重力和介質倒流撞擊啟閉件之前關閉閥門，因此這種直通彈簧驅動升降式止回閥也稱為“靜音”止回閥。
Swing-type check off er the least pressure drop and offer simple automatic closure; when fluid flow stops gravity and flow reversal closes valve.───旋啟式止回閥壓降最小，能夠完全自動關閉，即在介質流動停止、重力和介質倒流的狀態下自動關閉閥門。
Slamming of check valves is the result of failure of the valve disc to reach its closed position before the fluid flow reversal.───止回閥的撞擊現象，是由于在流體倒流之前，閥門的閥瓣沒有到達關閉位置造成的。
