J41W stainless steel shut-off valve is mandatory sealed valve, so that when the valve is closed, must exert pressure on the valve to force the sealing surface does not leak. When the medium enters from below the valve flap valve, the operating force required to overcome the resistance, the frictional force by the thrust generated by the pressure medium and the valve stem packing, the valve off the valve opening force larger than the force, so that the stem The diameter should be large, otherwise the stem benders failures occur. In recent years, from the emergence of self-sealing valve, the medium flow shut-off valve on the change into the valve chamber from above the valve, then at medium pressure, a small off valve force, and force open the valve, the valve stem diameter can be reduced accordingly. Meanwhile, in the role of the media, this form of valve is also relatively tight.
