Stainless Steel Union Ball Valve

Stainless Steel Valves

A ball valve is a type of shut-off valve that regulates the flow of a liquid or gas using a rotary ball with a bore. The medium can flow through or is blocked by rotating the ball a quarter turn (90 degrees) around its axis.

Ball valves are simpler and require less maintenance than other types of valves. The packing seal on the valve stem does not easily wear or fail because the stem rotates without axial movement. In addition, they are simple to disassemble and repair, and worn parts are inexpensive to replace.

Stainless Steel One-Piece  Ball Valve– has a single-piece cast body that houses the ball valve’s internal components. This is one of the most affordable and have a reduced bore.

Stainless Steel 2 Piece Ball Valve– is made up of two pieces of housing that are fitted together. The main piece houses the ball and has a connection to one end, while the other piece holds the internal components together and has a connection to the other end. The most common type of ball valve housing is two pieces. The two parts can be disassembled for cleaning, maintenance, and inspection, but the valve must be removed from the pipe.

Stainless Steel 3 Piece Ball Valve–  is made up of the housing for the valve’s internal components, which are fitted and held together by bolt connections at its two ends. The ends of the pipes are threaded or welded to the main pipe. Three-piece ball valves are used in applications that require frequent valve maintenance.

Features:
1. With simple structure, small volume and light weight, convenient for maintenance.
2. Easy operation: quick opening and closing by turning the handle 90 degree.
3. The sealing surface between the ball and valve is isolated from the media so that the passing medium  will not cause its erosion.
4. The direction of the medium is not restricted by the installation direction.
5. Good sealing performance and small fluid resistance.
6. Widely used to control and regulate the of media such as water, oil and non-flammable gas.
