YJ41W Special Oxygen Globe Valve product details

YJ41W Special Oxygen Globe Valve produced and sold by Baigang valve group is a forced-sealed valve, so the valve is closed, you must apply pressure to the valve to force the sealing surface does not leak. When the medium from the bottom of the valve into the valve six, the operating force needed to overcome the resistance is the stem and packing friction and the pressure generated by the media thrust, off the valve force than the valve opening force, so the valve The diameter of the rod should be large, otherwise it will happen to the top of the valve stem failure. In recent years, from the self-sealing valve appears, the flange of the media cut off the valve to change from the top of the valve into the valve chamber, then under medium pressure, the valve closing force is small, and open the valve force, valve The diameter of the rod can be reduced accordingly. At the same time, in the medium, this form of valve is also more stringent.

1, the oxygen valve is open, the valve opening height, 25% to 30% of the nominal diameter, the flow has reached its maximum, indicating that the valve has reached the fully open position. Therefore, the full-stop position of the valve, valve stroke should be determined.

2, small work schedule, opening and closing time is short.
3, good sealing, friction between the sealing surface is small, longer life expectancy.
