Cast steel American Standard flanged ball valve Q41F-150LBC

American Standard flange ball valve works by rotating the spool to make the valve unobstructed or closed. Ball valve switch lightweight, small size, can be made into a very large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and the ball surface is often in the closed state, is not easy to be eroded by the medium, in various industries are widely used. Two-piece flange ball valve has its own unique superiority, such as switching without friction, sealing is not easy to wear, opening and closing torque is small, so that you can reduce the specifications of the actuator fitted. Widely used in petrochemical city water supply and drainage requirements of strict working conditions.

Working Principle

American Standard flange ball valve closing member is a ball with a hole (or part of the ball), the ball with the stem rotation, to achieve the valve open or close. Ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of flow of media. Flange ball valve ball is floating, under the action of medium pressure, the ball produces a certain displacement and tightly pressed on the sealing surface of the outlet end, to ensure that the outlet end of the seal. In a variety of valves, the ball valve flow resistance is small, the ball valve is open, the ball channel, the valve body channel and connecting pipe diameter is equal and into a diameter, the medium can flow through almost no loss.

Product Characteristics

1. Easy to install, can be installed in any direction in any part of the pipeline.
2. High-quality sealing ring material has the performance of high temperature, high pressure and corrosion resistance.
3. The channels in the valve body are flat and smooth, and can transport viscous fluids, slurries, and solid particles.
4. Widely used for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
