1) The Ball Valve for Natural Gas channel is flat and smooth to facilitate pipeline sweeping and cleaning, and can transport media such as slurry and solid particles.
2) Ball Valve for Natural Gas uses PTFE (Teflon) and other materials as a seal, which has good lubricity and elasticity, small friction with the ball, and long service life.
3) Ball Valve for Natural Gas needs to rotate 90° when opening and closing fast, which is convenient and fast.
4) Ball Valve for Natural Gas selects corrosion-resistant and sulfur-resistant materials;
5) The fluid resistance of Ball Valve for Natural Gas is small. When fully open, the cross-sectional areas of the ball passage, valve body passage and connecting pipe are equal, and they are in a straight line. The medium flows through the ball valve, which is equivalent to flowing through a straight-through pipe. The fluid resistance of the ball valve in the valve is relatively small.
5) Ball Valve for Natural Gas is equipped with manual, worm gear drive, pneumatic, electric (explosion-proof) to realize remote automatic control. The ball valve larger than DN150 is driven by worm gear, and the fixed ball valve larger than DN200 is used;
1) Ball Valve for Natural Gas is suitable for gas pipelines, liquefied petroleum gas pipelines, natural gas pipelines, gas pipelines and other general working media;
2) The Ball Valve for Natural Gas stainless steel valve body is also suitable for applications in various industries, such as oxygen, hydrogen peroxide, methane, and ethylene, in harsh working conditions.
