Q41N / F natural gas ball valves are made of shaped polytetrafluoroethylene (PTFE) filler, suitable for most high and medium pressure gas transmission occasions. The handle operates smoothly and the O-ring is used to prevent external impurities from entering the valve. And maintain the valve's long-term sealing performance. The ball valve larger than DN150 is driven by worm gear. Gas ball valve is suitable for opening and closing devices of medium and small caliber pipelines under various pressures, temperatures and media, which can be controlled to turn on or cut off the pipeline medium. The pressure and diameter of the ball are limited when it is pressed on the outlet valve seat by the medium pressure.
Product features
1. The ball valve passageway is smooth and smooth, which is convenient for pipeline sweeping and cleaning. It can transport slurry and solid particles and other media.
2. PTFE (polytetrafluoroethylene) and other materials are used as sealing materials, with good lubrication and elasticity, small friction with the sphere, long service life, quick opening and closing, opening and closing only need to rotate the sphere 90 degrees, convenient and rapid
4. The fluid resistance of the ball valve is small, and the cross-section area of the ball passage, valve passage and connecting pipeline is equal when the ball valve is fully opened, and the medium flows through the ball valve in a straight line, which is equivalent to the flow through a straight pipe, and the fluid resistance of the ball valve is the smallest in all kinds of valves.
5. The remote automatic control can be realized by manual, worm wheel drive, pneumatic and electric (explosion-proof) equipped, which can meet the user's various operating conditions.
