A gate valve that is suggested for media that doesn't cause disintegration, erosion, or any condition that could harm the stem material 

Likewise called as the visually impaired stem wedge entryway valve and the revolving stem door valve. In this valve, the stem goes to open and close the plate or door. Notwithstanding, the stem doesn't go up nor down as it pivots. This implies that as the stem pivots, it movements towards or away from the valve, which further controls the door to open or close media stream. 

The primary benefit of a non-rising stem entryway valve is it occupies little room. This implies that it is appropriate for applications that have restricted space.
