The durable special globe valve for liquefied gas manufactured by JQF Valve manufacturer is a forced-seal valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to prevent leakage at the sealing surface. When the medium enters the valve from below the valve disc, the operating force must overcome resistance including the friction between the valve stem and the packing, as well as the thrust generated by the medium pressure. The valve diameter should be large enough; otherwise, valve stem bending failure may occur.
