Gas ball valve

 

Q41N / F gas ball valve forming PTFE packing, suitable for most high pressure gas transmission occasions, smooth handle operation torque, O-rings to prevent external contaminants from entering the internal valve. And maintain long-term sealing performance valves, ball valves larger than DN150 using worm gear drive. Gas Ball Valve is suitable for medium and small-caliber pipeline pressures, control the opening and closing device is turned on or cut off the pipeline medium temperature and media; sphere pressed by media pressure on the outlet end of the valve seat, the use of pressure and path subject to certain restrictions. using 90 ° transmission, so switch easily and quickly, can be implemented quickly open and close.
Product Features
1, valve channel to facilitate smooth sweep line pipe cleaning, slurry and solid particles can be transported and other media
2, the use of PTFE (polytetrafluoroethylene) as a sealing material, has good lubrication and elasticity, and the sphere of friction, long service life 3, open and close rapidly, just put the ball rotated 90 ° when opening and closing, convenient and quickly
Fluid resistance 4 ball, when the ball full channel cross-sectional area, the body channels and connecting pipes are equal, and figured in a straight line, the medium flowing through the valve, a period equivalent to the flow-through tubes in various types of valves the minimum fluid resistance ball
5, configured with manual, worm drives, pneumatic, electric (explosion) can achieve remote automatic control, can meet a variety of working conditions requirements of users.
