Q41F American standard flange ball valve product introduction:
 
American Standard Flange Ball Valve is designed and manufactured by API 600 and API 602. It is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Q41F American standard flange ball valve integral silica sol precision casting valve body, the valve body surface is fine and beautiful, no need to polish. Designed with anti-static, refractory structure, valve body and other components selected from high-quality stainless steel and acid-washed, passivated, inspected and tested with pure tap water without any grease for high-pressure sealing test, through the above special process, such ball valve not only operates Fast and flexible, low flow resistance, safe and reliable, and long service life (small seal flushing).
 
working principle:
The working principle of the American standard flange ball valve is to make the valve unblocked or blocked by the rotary valve love. The ball valve switch is light in weight and small in size, and can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and the spherical surface are often closed, and is not easily eroded by the medium, and is widely used in various industries.
 
The main purpose:
American standard flange ball valve uses polymer materials such as polytetrafluoroethylene and para-polyphenylene. The sealing performance is good, but the material is relatively soft. Because the material is soft, but to achieve a certain sealing specific pressure, it is bound to increase the opening and closing torque. Suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. This product can be widely used in the control systems of paper, petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial sectors.
 
Features:
1, full diameter, floating / fixed ball
2, the middle flange bolt connection
3, anti-shooting valve stem
4, fire and anti-static structure
5, American standard structure improved
6, opening and closing positioning mechanism
7, worm gear operation matching
8, standard flange connection
