Stainless Steel Ball Valve

    Grade: 304, 316, etc.


    Size: 1/4”-4”


    Type: One Piece, Two Piece, Three Piece

Ball valve, a valve with opening and closing parts (spheres), is driven by the stem and rotating around the axis of the ball valve. Can also be used for fluid regulation and control, hard seal v-ball valve its v-ball core and surfacing hard alloy metal seat between a strong shear force, especially suitable for containing fiber, small solid particles and other media.

The multi-pass ball valve in the pipeline can not only flexibly control the media confluence, shunt, and flow direction switch, but also can close any channel and make the other two channels connected.

Valves of this type shall generally be installed horizontally in the pipeline. Ball valve according to the driving mode is divided into: pneumatic ball valve, electric ball valve, manual ball valve.

A three piece ball valve is preferred wherever regular cleaning is required. The valve body is composed of 3 separate pieces held together by bolts, which can be easily removed for cleaning and servicing. A unique advantage of the 3 piece valve design is that the ball valve ends can remain threaded into the pipe, while the center section containing the ball can be removed. These 3 piece ball valves have been specifically designed to be easily disassembled, cleaned, and reassembled. 3 piece stainless Steel ball valves also called 3 SS ball valves, are widely used for a variety of sanitary applications that are required for pharmaceutical and food/beverage industries.

The 2 piece stainless steel ball valve is probably the most widely used ball valve. The 2 piece ball valve will open or shut off flow on most liquids and gases quickly and easily and is suitable for just about any application where a simple on/off action is needed. Flow rate can also be controlled by partially opening or closing the valve to various degrees. Also referred to as a two-way ball valve, since it allows flow in any direction straight through from inlet to outlet. Being threaded ball valves they are quick to install and easy to use, requiring no tooling for installation. The two piece ball valve is the best priced full port ball valve (full bore), allowing the inside diameter of the pipe to remain constant and unrestricted. This means that the 2 piece SS ball valve has no pressure drop and keeps the flow rate high.

The One Piece Ball valve as the name suggests is made out of one body piece unlike the 2 and 3 piece. This means the valve cannot be taken apart for cleaning. The advantage is that the valve will be low cost and robust. As a result of the valve body being one piece is that a smaller ball has to be used leading to a reduced port, more commonly called a reduced bore. This means that flow is reduced through the valve, since the ball bore is one size smaller than the pipe size.
