Ball valve for gray cast iron material soft seal ball valve, cast iron ball valve used in the working temperature ≤150ºC water, steam and other non-corrosive media pipeline, for opening and closing; Its biggest advantage is that the opening and closing quickly. Its affordable price is the normal temperature water medium pipeline application more common a valve product.
If the pipeline pressure is required to be above 1.6Mpa, the pipeline temperature is above 150ºC, and the medium is water, steam, and oil, please choose the cast steel ball valve product model is Q41F-16C or above or Q41H series
Q41F-16 Cast iron ball valve advantages:
1, the fluid resistance is small, the full diameter ball valve basically no flow resistance.
2, simple structure, small size, light weight.
3, tight and reliable. It has two sealing surface, and the sealing surface material of the ball valve is widely used in various plastics, which has good sealing property and can achieve complete sealing. It has also been widely used in vacuum systems.
4, easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.
5, easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium. When the medium passes, the sealing surface of the ball valve will not be eroded.
7, wide range of application, diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
8, because the ball valve in the opening and closing process has wipeability, so it can be used in the medium with suspended solid particles.
