Product Description

The following is the detailed description of ball valve. If you have any need about other valves, please check the home page of YOONAD Valve and feel free to contact me anytime.

The most common types of manual ball valves are the 1-Piece, 2-Piece and 3-Piece. Another relatively common type is the 3-way ball valve, these 4 types account for the vast majority of the most often used valves.

One Piece

A One-Piece has valve body cast out of a single piece of material. This means that there no joints in the body which eliminates the risk of leaks. The one-piece has a smaller body than the other valves making it the most cost effective. This also results in a smaller ball which means one-piece valves always have a reduced port. This means the internal diameter of the pipe decreases by one size at the point where the valve is installed. they are generally used where cleaning is not a concern and where the possibility of particle build up is low.

Two Piece

A Two-Piece has a valve body cast out of two pieces that thread together. The two-piece has a larger body which allows for a larger ball which means a full port is possible. This means the internal diameter of pipe the remains constant throughout the pipe, once the valve is installed. They are the most commonly used among all the ball valve types and are good for mixtures and applications where an optimal flow rate is preferred. The Valve body can be dismantled for cleaning and to service the seals, however the valve will have to be removed from the pipe, unlike the three piece.

Three Piece

A Three-Piece has valve body cast out of three pieces that are held together by bolt connections fitted to each of the two ends. The three-piece also has a larger body which allows for a larger ball with a full port. They are ideal for applications where regular maintenance and cleaning is required. By loosening the bolt connections the valve separates into three parts and the internal ball and seats can be accessed without removing the two ends connected to the pipe. This makes them ideal for food & beverage applications and in pharmaceutical industries where sanitation and regular cleaning is required.

Three Way

These mulit-port valves are used in mixing or splitting flow (T-Port) and also for diverting (L-Port) multiple streams of fluid. This is achieved by means of a L-shaped or T-shaped bore in the ball. On top of this they also open and close the flow to multiple fluid streams. There are two types of 3-way ball valves L-Port and T-Port:

• L-Port
• Used as diverter valves directing flow from a single inlet to one of two outlets.
• Also used as selector valves selecting one of two inlets to flow to a single outlet.

• T-Port
•  Used as mixing valves combining flow from two inlets into a single outlet.
• Also used for splitting flow from a single inlet to two outlets simultaneously.

They are commonly used in various industries such as oil and gas, petrochemical, power generation, chemical processing, and water treatment, where reliable control of high-pressure fluids or gases is required. High pressure ball valves offer several advantages, including quick and easy operation, excellent sealing capabilities, minimal pressure drop, and durability in demanding environments.
