Why Stainless Steel Ball Valves Have A Certain Position In The Valve Industry
The working principle of 3 Piece Ball Valve is to make the valve open or closed by rotating the valve ring. The stainless steel ball valve is light and small in size. It can be made into a large diameter, has reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, and it is not easy to be eroded by the medium. It is widely used in various industries. Since stainless steel ball valves usually use rubber, nylon and polytetrafluoroethylene as valve seat sealing ring materials, its operating temperature is limited by the valve seat sealing ring material. The cut-off effect of the stainless steel ball valve is achieved by the metal ball being pressed against the plastic valve seat under the action of the medium (floating ball stainless steel ball valve).
The ball-type closing part of the stainless steel ball valve can automatically locate in position, and the working medium is reliably sealed on both sides. When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not cause erosion of the sealing surface. It has a compact structure and light weight. It can be considered a reasonable valve structure suitable for low-temperature medium systems.
The stainless steel ball valve body is symmetrical, especially the welded valve body structure, which can withstand the stress from the pipeline well, and the closing parts can withstand the high pressure difference when closing.
