2 pc Stainless Steel Ball Valve

It is obvious that a stainless steel ball valve is a ball valve that is made of stainless steel. Therefore, this kind of valve has the common features of a ball valve that is endurable, easy to operate and repair and has good on/off  property, due to the basic of a ball valve, which is a valve with a spherical disc, which is the control part. The sphere has a hole through the middle so that when the port is in line with both ends of the valve, flow will occur. As a stainless steel ball valve is made of stainless steel material, it would certain benefits from this design. Its characteristic is largely depend on its components and its crystalline structure .stainless steel is also called inox steel or inox from French "inoxydable". Generally speaking, it is a steel alloy with a minimum of 10.5 or 11% chromium content by mass.Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain-proof.

There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Stainless steel is used where both the properties of steel and resistance to corrosion are required.

Two-piece ball valve is consisting of a valve body and a bonnet. It is assembled by two parts, that is how its name comes from.. It is widely used because when the lutation that is before valve body and bonnet goes wrong, people can stop revealing by closing the valve.

There are several structure features of two- piece ball valve.

Firstly, there is no friction when open and close, which totally sloves the problem of the leak-proofness causing form friction between the sealing surfaces in traditional valve.

Secondly, it has top entry structure design. People can check and repair the valve assembled on the pipe directly, which can reduce the number of stopping car for the purpose of installing, which finally lower the cost.

Thirdly, it has the design of single valve seat, which eliminate the bad effection causing by the unconventional pressure of the medium in the valve chamber.

Fourthly, it has the design of low torque, which only needs a tinny handlebar to open.

Fifthly, it has the design of wedge shape leak tight structure, which ensures the leak tightness under all kinds of working conditions.

Sixthly, it has the design of self-cleanning struction of sealing surface. When the ball lurches away the valve seat, the flow in the pipeline passes the ball sealing surface homogeneously, which not only eliminate the effect causing from high-velocity fluid eroding the valve seat, but also rushes out the deposits on the surfaces.
