Sulfur resistant stop valve

Product description

KJ41Y-16~100C,P,R

Product description

The opening and closing part of the stop valve is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves in a straight line along the center line of the fluid. The movement form of the valve stem (general name: concealed rod) and the lifting rotary rod type (general name: exposed rod) stop valve is a valve in which the closing part (disc) moves along the center line of the valve seat. According to this movement form of the valve disc, the change of the valve seat opening is directly proportional to the valve disc stroke. Because the valve stem opening or closing stroke of this kind of valve is relatively short, and has a very reliable cut-off function, and because the change of valve seat opening is in positive proportion to the stroke of valve disc, it is very suitable for flow regulation. Therefore, this type of valve is very suitable for cut-off or regulation and throttling.
