Stainless steel globe valve  

Product overview Globe valve,also known as the cut-off valve, belongs to the forced sealing valve,so when the valve is closed,pressure must be applied to the valve disc to force the sealing surface does not leak. Whenthe medium enters the valve from below the disc,the resistance that the operation force needs toovercome is the friction force of the rod and the packing and the thrust produced by the pressure ofthe medium. The force of closing the valve is larger than that of opening the valve,so the diameterof the castron should be large, otherwise the failure of the stem top bending will occur. According tothe connection mode, it is divided into three kinds: flange connection,silk connection and weldingconnection. From the appearance of the sealing valve,the medium flow of the globe valve ischanged from the top of the valve into the valve chamber,then under the action of the mediumpressure, the force of closing the valve is small, and the force of opening the valve is large,an…
