- They provide leak-proof service.
- They open and close quickly.
What is full port or reduced port valve?
Sometimes called “full bore,” a full port ball valve is a special valve design that allows for unrestricted flow when the valve is opened. Full port valves have larger bodies than standard valves. This larger body houses a larger ball and larger opening inside. Full port valves have openings the same size as the surrounding pipe.

What is meant by full port ball valve?
A full port or sometimes called full bore, ball valve has a straight flow path where there is not a reduction of flow as it travels through the valve. In other words, the internal diameter of the pipe or tubing at the inlet and outlet of the valve has the same diameter as the interior of the ball valve.
What is the difference between a full port and standard port ball valve?
The difference can be summed up fairly simply: Full port: The valve port is the same diameter as the pipe. Standard port: The valve port is smaller than the pipe's diameter. Exact port size varies but generally the port size is that of one pipe size smaller than the valve in question.
Is full port and full bore the same?
There is absolutely no difference between the terminology full port and full bore; they are both the same thing.

What is full flow valve?
Full flow ball valves are designed with a full port to maintain a high flow rate while minimizing possible pressure drops.
How many types of ball valves are there?
Types. There are five general body styles of ball valves: single body, three-piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled.
What is CWP on valve?
Cold working pressure (CWP) indicates the valve's maximum pressure rating at temperatures between -20°F to 100°F. This is commonly referenced alongside the valve's pressure rating.

What is a V ball valve?
V-ball valves feature a quarter turn (90°) ball rotation, allowing them to operate and shut off at much higher working pressures. Because of this, smaller lower torque actuators can be used, which results in cost savings and higher efficiency in the user's application.
What is a full port ball valve?
Sometimes called “full bore,” a full port ball valve is a special valve design that allows for unrestricted flow when the valve is opened. Full port valves have larger bodies than standard valves. This larger body houses a larger ball and larger opening inside.
Is 3/4 pipe size smaller than 1/2 pipe size?
Actually, it is precisely one pipe size smaller. For instance, a 3/4” reduced port valve has a 1/2” pipe size ball opening. This smaller opening causes an increase in velocity. Generally, full port ball valves are more expensive than standard or reduced port valves. Depending on the application, one or the other may be beneficial.
What is a full bore ball valve?
A full bore ball valve has a low flow resistance (high flow coefficient), about the same as a straight piece of pipe. This means a full bore ball valve causes very little pressure drop across the valve. The flow path through a standard bore ball valve is narrower with a higher resistance to flow (lower flow coefficient).
What is the difference between a ball valve and a full bore valve?
The pressure difference across a valve is greater for a standard bore ball valve than it is for a full bore valve. Full bore ball valves tend to have little or not pressure difference across the valve.
How does a ball valve work?
The handle on a ball valve opens the valve when it turns the ball to align with the pipe or tube so that it is pointing the same direction as the pipe. This allows flow to pass through it. The valve handle can also turn the ball so that the bore is at a right angle or 90 degrees to the flow. This closes the ball valve.
What is a valve in a pipe?
Generally, valves are devices used to control the flow of a gases or liquids through a closed tube or pipe system. Flow through a valve can be relatively unobstructed when it is completely open. Flow stops when the valve is completely closed. A ball valve consists of a valve body with a rotatable ball in it.
Why are ball valves not suited for regulating flow?
Ball valves are not well suited for regulating flow. This is because ball valves use a relatively soft ring-shaped valve seat to create a tight seal. When they are partially open, pressure is applied to only a portion of the valve seat. This can cause the valve seat to warp and reduce its ability to provide a good seal causing it to leak.
What is the bore diameter of a 3/4 inch valve?
An example to help make this clearer. The bore in a 3/4-inch size full bore ball valve is 3/4-inch in diameter. The bore in a 3/4-inch size standard bore ball valve is 1/2-inch. This is because the balls in standard bore valves are sized in proportion to their valve bodies and bore sizes. In practice, this makes the bore diameter ...
What is the flow path through a full port valve body?
Summary: The flow path through a full port valve body is the same size as the flow coming into the valve and leaving it via its tube or pipe connections. Standard port valves have smaller bodies overall with a corresponding narrowing inside the valve body.
All-Purpose Kinvalve Full Port Ball Valve with Zero Flow Resistance

What is a full port valve?
A full port or more commonly known full bore ball valve has an over-sized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines which require pigging. ...
What is a reduced port ball valve?
In reduced port or more commonly known reduced bore ball valves, flow through the valve is one pipe size smaller than the valve's pipe size resulting in flow area being smaller than pipe.
When to use standard ball valve?
Standard (reduced)-port ball valves are used where pressure drop, turbulence in the flow and material characteristics are not a concern.
What is the difference between a full bore and a reduced bore valve?
But the major difference between a full bore valve and a reduced bore valve is this: For the full bore valve, the bore diameter i.e hole in the ball has the same internal diameter as the pipe, whereas a reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on.For example, ...
Why use a full port ball valve?
The flow resistance and pressure drop in a standard port valve can starve the system of fluid by reducing flow, may lead to more cavitation and valve wear, and can quickly cause separation between solids and fluids ...
What is a full port valve?
Full port means that the bore size is about the same as the pipe you’ll connect the valve to. Standard is usually one nominal pipe size below that. So, for example, let’s say you need a forged ball valve for a ¾” pipe. If you need a full port valve, then the hole will be about ¾” in diameter.
How does a port valve work?
Standard port valves have a bore size in the ball about 1 standard size smaller than the pipe they connect to. If you’re in the market for a metal seated ball valve, you likely know how they work. However, just in case, let’s quickly go over how a ball valve controls flow. Inside the valve is a ball which you can rotate with the handle.
What industries use full port valves?
Otherwise, standard port can help save space and money. Here are some industries that may need full port ball valves: Petrochemical. Oil refining.
Is it better to have a full port or a standard port?
While standard port is fine for most applications, there are some benefits of choosing a full port option. Port size will affect the valve’s flow coefficient. Full port valves have lower flow coefficient, meaning it’s pretty close to flow in a straight pipe.
The full port valve design
A full port or sometimes called full bore, ball valve has a straight flow path where there is not a reduction of flow as it travels through the valve. In other words, the internal diameter of the pipe or tubing at the inlet and outlet of the valve has the same diameter as the interior of the ball valve.
The standard port valve design
A standard port also has a straight flow path, but there is a flow restriction that produces a pressure drop as the flow passes through the valve.
How do you determine if you need a full port ball valve or if a standard port will suffice?
Some applications require a full port ball valve due to a characteristic of their application; for example, if low flow resistance is needed. In the case of a pump suction pipe where a pressure drop can impact the performance of a pump, a full port valve may be the best choice to maintain flow.
