Products Detail

Globe valve, also known as the cut-off valve, belongs to the forced sealing valve, so when the valve is closed, it must apply pressure to the disc, in order to force the sealing surface does not leak. When the medium from the lower part of the disc into the valve, the operating force to overcome the resistance, is the friction of the stem and packing and by the medium of the pressure generated by the thrust, the force of the valve closed than the force of the valve, so the diameter of the stem to be large, otherwise it will occur valve top bending failure. There are three types of connection: flange connection, screw connection and welding connection. From the seal of the valve, the medium flow of the globe valve is changed from the upper part of the disc into the valve chamber, then under the pressure of the medium, the force to close the valve is small, and the force to open the valve is large, the diameter of the stem can be reduced accordingly. At the same time, in the medium action, this form of the valve is more stringent. Our country valve "3 turn to give" once stipulated, the flow direction of stop valve, all USES from top to bottom. When the globe valve is opened, the opening height of the disc is 25% ~ 30% of the nominal diameter. So the full open position of the globe valve should be determined by the stroke of the disc.
