Srpski језик In plunger globe valves, valve clack and valve seat are designed by the plunger principle. The valve clack is polished into a plunger and connected to the valve stem. The sealing is achieved by two elastic seal ring that sheathed on the plunger. The two elastic seal ring are separated by a sleeve ring and the rings around the plunger are held tight by a load applied to the bonnet by the bonnet nut. Globe valves are mainly used for opening and closing flow.
View DetailsSend InquiryLift Globe Valve is used to cut off the flow of media and is suitable for occasions that need to be opened frequently. Lift Globe Valve is most commonly used in chemical production. Milestone Valve Co. Ltd specializes in the production of Lift Globe Valve. The products are of high quality, stable performance, and are used in various fields of industry with excellent functions.
View DetailsSend InquiryCast Iron globe valve is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so Cast Iron The diameter of the valve stem of the globe valve should be large, otherwise the valve stem will bend up failure.
View DetailsSend InquiryThe Cryogenic Globe valve is composed of valve body, disc, stem, bonnet, handwheel and seal. The bonnet is of lengthened neck structure. It is characterized by double compression sealing structure composed of upper packing and lower packing. The medium flow path is low in and high out. The inlet channel of the valve body is below the sealing surface of the valve seat, and the outlet channel of the valve body is above the sealing surface of the valve seat.
