2PCS Forged Steel Flanged Floating Ball Valve (Q41F)
Product Description
(1) The ball valve has low fluid resistance and has the lowest flow resistance (actually zero).
The Ball valves generally have two structures of reduced diameter and non-reduced diameter channels. Regardless of the structure, the flow resistance coefficient of the ball valve is relatively small. Especially the so-called full-flow type, that is, the ball valve that does not reduce the diameter, because the channel diameter is equal to the inner diameter of the pipe, the local resistance loss is only the friction resistance of the pipe of the same length, that is, the flow resistance of this ball valve is the smallest among all valves.
(2) The opening and closing of the ball valve is quick and convenient.
Because the ball valve generally only needs to rotate the handle 90° to complete the fully open or fully closed action, it is easy to achieve rapid opening and closing. It can realize fast opening and closing, and the opening and closing time of some structures is only 0.05-0.1s to ensure that it can be used in the automation system of the test bench. When opening and closing the valve quickly, there is no shock in operation.
(3) The ball valve has good sealing performance.
At present, most of the valve seats of ball valves are made of elastic materials such as polytetrafluoroethylene, and the sealing pair composed of metal and non-metal materials is usually called a soft seal. Generally speaking, the tightness of the soft seal is easy to ensure, and the processing accuracy and surface roughness of the sealing surface are not very demanding.
(4) The ball valve has a long service life.
Because PTFE has good self-lubricating properties, the friction and wear with the ball is small, and due to the improvement of the ball processing technology, the roughness is reduced, thereby increasing the service life of the ball valve. According to reports, the American W-K-M Company conducted a life test on the ball valve in the test room, and the number of switching times exceeded 100,000.
