Stainless steel globe valve is a forced seal valve

Date: [2018-10-22] Click rate:

The stainless steel globe valve is a compulsory sealed 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 under the stainless steel cut-off valve disc, the resistance to be overcome by the operating force is the friction between the valve stem and the 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. Therefore, the diameter of the valve stem should be large, otherwise the failure of the valve top bending will occur.


The principle of stainless steel globe valve is developed by using the valve stem pressure app, pressing the disc sealing surface to the valve seat sealing surface, closing the valve and blocking the flow of medium. There are three types of stainless steel globe valve: manual stainless steel globe valve, pneumatic stainless steel globe valve and electric stainless steel globe valve.
