Q341 American Standard floating ball valve（Description）

Q341F American standard floating ball valve belongs to the soft seal floating ball valve, the design and manufacture standard is API 600, API 602, in the pipeline is mainly used to cut off, distribution and change the flow direction of the medium. American Standard soft seal floating ball valve mainly uses a ball with a circular channel as the opening and closing part, the opening and closing part is a ball with a hole, rotating around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel.

Q341F American standard floating ball valve switch light, small size, can be made into a large diameter, reliable sealing, low friction coefficient, small operating torque, a variety of seat materials, wide range of adaptation, simple structure, convenient maintenance, sealing surface and sphere often in the closed state, not easy to be eroded by the medium, in various industries have been widely used. Applicable medium: water, gas, oil, natural gas and acid and alkali corrosive medium.
