Valve is closed parts (valve / valve) moving along the centerline of the valve seat. According to valve (Fa Xin)this mobile form, seat through the mouth of the change iswith the valve flap valve (Fa Xin) the proportional relationship between the trip. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and through the mouth of the valve (valve) stroke is proportional, is very suitable for flow regulation.Therefore, this type of valve is suitable for cutting orregulation and throttle use.
In the opening and closing process, because the valve(valve) and valve sealing surface friction forces between the small, and therefore wear.
The opening height is small.
Usually in the valve body and valve (Fa Xin) is only one sealing surface, so the manufacturing process is good,easy to repair.
