The Stainless steel forged oxygen globe valve is a mandatory sealing valve. When the medium enters from below the valve disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the force of the valve stem The diameter should be large, otherwise the valve stem will bend up failure.
