The face seals provide constant guiding throughout the valve stroke, maintaining continuous contact with the gate.
在阀门闸板运动的全过程中，密封面都对闸板提供恒定的引导，保持与闸板连续稳定的接触。
By this, force acting in the direction of closing a valve body (41) ACTS on it through the diaphragm (42), maintaining the shutoff valve (40) closed.
从而经由隔膜(42)对阀体(41)在关闭的方向上施力，维持断流阀(40)关闭的状态。
Simple design allows an effortless means of maintaining the valve with minimal down-time.
简单的设计使保养维修变得更加简单，并使停机时间最小化。
Moreover, the self maintaining switch is relatively far from the pressure limiting exhaust valve, thereby avoiding the operator from being scalded by the steam.
而且自持开关离开限压排气阀较远，操作者能避免蒸汽烫伤的危险。
