The Stainless Steel Ball Valve, as its name suggests, is a valve whose use a hollow,perforated and pivoting ball to control flow through it. The ball valve is in the open position when this central port is aligned in the same direction as the connected piping, as this positioning allows fluid or gas to flow through it. The valve rotates to the closed position when the door becomes perpendicular, blocking the flow path and preventing any substances from continuing to circulate inside the pipeline. The ball valve is part of the ¼ turn family because to obtain the closing or opening, only a quarter of rotation is required, that is, a 90 ° movement.
 
       The ball valve is a notable industrial choice thanks to its airtight and reliable seal when in the closed position. This makes them particularly ideal for industries that transport chemicals or potent gases that require fast, secure closure, such as natural gas.
 
        Ball valves are durable, perform well after many cycles and are reliable, closing securely even after long periods of disuse . These qualities make them an excellent choice for closing and flow control applications.
 
Type of stainless steel ball valve
According to its construction, the ss ball valve can be 1 piece, 2 piece and 3 piece.
 
It is a monobloc valve, without parts, that is, consisting of a single block. In this case, the ball assembly is of the floating type and in the side entry style.
 
It also named split valve, has a structure consisting of two parts divided symmetrically or asymmetrically: the body and the cover. When the division is symmetrical, the stem is integral to the sphere. In the case of asymmetric, stem and sphere are separate elements. The parts are joined using thread.
 
The Tripartite valve has a structure consisting of three parts: a body and two covers. It has the great advantage that it is not necessary to disassemble it from the piping to replace the sealing rings and body joints. The parts are joined using screws.
