Product Description

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.

 

• Pressure rating up to 6000 psig (413 Bar) at 70ºF (21ºC) with PCTFE seats
• Temperature rating from -65ºF to 350ºF (-54ºC to 177ºC) with standard PCTFE seat
• Compact design
• Straight through design for max. flow rate
• Body materials available in 316 stainless steel and brass
• 100% factory tested

• Ease of Use: They open and close quickly using minumal force with a simple 90 degree (quarter-turn) of the handle and require no tools for operation. 
• Quick Installation: They are quick and easy to install using simple threaded ends as a method of connecting in-line to an application.
• Versatile: They are good for high pressure, high temperature and high flow making them suitable for a wide range of industrial applications.
• Durable: Their simple robust design provides resistance to general wear and tear ensuring a long service life of reliable use.
• Reliable: They are designed for repeatable use of leak free service, that is to repeat their function of opening and closing flow in the same way for the life of the valve.
• Cost Effective: They are the most cost effective of all the valves. 
• Low Maintenance: Since they are low maintanance and require little to no service, this results to additional long term cost savings.
• No Lubrication required: The seats holding the ball function well in wet and dry situations.
• Low Pressure Drop: They have a high flow capacity and low pressure drop due to the size of the bore in the ball. when fully open there is little to no resistance to the flow of fluid.
• Compact: Smaller than other options like gate and butterfly valves.

Ball Valve Components

Although there are numerous parts making up the valve the basic components are made up of the following:

The Valve Body

Also referred to as the valve housing or shell, it contains all the inner components of the valve. Usually composed of a rigid metal, in this case Stainless Steel, it protects all the internal components and keeps them in the correct position and aligned for proper functioning. It also facilitated access for the external handle to connect with and rotate the internal ball, via the stem. The valve body comes in three assembly options: one-piece, two piece and three-piece designs.

The Rotary Ball

This is the part that gave the valve its name. It is a ball that has "flow path" known as a bore, through the center that allows the medium to flow through it. The ball is rotated by the stem, which either opens the flow when the bore is in-line with the pipe or closes the flow when the bore is perpendicular to the flow. There are two types of bore design: Full port and Reduced port.

The Stem

Also referred to as the shaft, it connects the external handle that rotates the inner ball. The Stem has washers and packing rings to ensure a tight seal and to prevent any leaks. The stem is rotated as the handle is turned, which in turn rotates the ball, opening and closing the flow.

The Seat

The Seat sits between the ball and the valve body and ensures a water tight seal. There are two seats that sit on either side of the ball and are usually composed of (PTFE).

The Handle

The handle is also often called the lever. it a standard ball valve it is the manual way used to turn the ball valve to the open or closed position.
