First, the selection and setting of the valve:

(1) The valves used on the water supply pipeline are generally selected according to the following principles:

1. When the pipe diameter is not more than 50mm, it is appropriate to use the globe valve, and when the pipe diameter is more than 50mm, the gate valve and butterfly valve are used

2, need to adjust the flow, water pressure when the use of regulating valve, stop valve

3, the part that requires small water flow resistance (such as the water pump suction pipe), should use gate valve

4. Gate valves and butterfly valves should be used on the pipe section where the water needs to flow bidirectional, and stop valves should not be used

5. Butterfly and ball valves should be used for parts with small installation space

6, in the pipe section that is often opened and closed, it is appropriate to use a stop valve

7. Multi-function valve should be used on the water pump with larger diameter

Second : The following parts of the water supply pipeline should be provided with valves:

1, the residential district water supply pipeline from the municipal water supply pipeline introduction pipe section

2. The nodes of the outdoor ring pipe network in the residential district should be set according to the separation requirements. When the annular pipe section is too long, it is advisable to set a segmented valve

3. The branch pipe from the water supply main pipe in the residential area or the household pipe

4, household pipe, water meter and branch risers (bottom of risers, vertical ring pipe network risers, upper and lower end)

5, the main pipe of the ring pipe network and the connecting pipe of the branch pipe network

6, the indoor water supply pipe to the household, public toilet, etc., the water distribution point on the water distribution branch pipe is set at 3 or more

7, the water pump out of the water pipe, the suction pump of the self-filling pump

8, water tank inlet, outlet pipe, drainage pipe

9, equipment (such as heaters, cooling tower, etc.) water supply pipe

10, sanitary appliances (such as large, urinal, wash basin, shower, etc.) of the distribution of water pipes

11, some accessories, such as automatic exhaust valve, pressure relief valve, water hammer eliminator, pressure gauge, sprinkler hydrant, etc., pressure reducing valve and reverse flow preventer before and after

12, the lowest part of the water supply network should be set up a drain valve

Third :The check valve should generally be selected according to its installation position, the water pressure before the valve, the sealing performance requirements after closing and the size of the water hammer caused by closing

1. When the water pressure before the valve is small, swing, ball and shuttle check valves should be selected

2. When the sealing performance after closing is strict, a check valve with a closing spring should be selected

3, when the water hammer is required to be weakened and closed, it is appropriate to choose a quick closing silencing check valve or a slow closing check valve with a damping device

4. The valve break or spool of the check valve should be able to close itself under the action of gravity or spring force

Fourth : Check valves shall be installed on the following sections of the water supply pipeline:

Lead into the tube; On the inlet pipe of a sealed water heater or water equipment; Pump out of the water pipe; The inlet and outlet water pipes are used in the water tank, water tower, and outlet pipe section of the highland pool.

Note: Pipe sections equipped with pipe backflow preventers do not need to install check valves.

Fifth The following parts of the water supply pipeline shall be equipped with exhaust devices:

1, intermittent use of the water supply network, the end of the network and the highest point should be set up automatic exhaust valve

2, the water supply network has obvious fluctuations in the accumulation of air pipe section, has been set in the peak point of the section of automatic exhaust valve or manual valve exhaust

3, pneumatic water supply device, when the automatic air supply type air tank is used, the highest point of the water distribution network should be equipped with an automatic exhaust valve

A lot is to be known about the ball valve, from its different types, its vast uses and applications, and even the materials used to produce it. Another important thing to note about ball valves is the kind of port it has. Read on if you want to know more about ball valve ports.

Full port or full bore valves and standard port of standard bore valves are the two main ball valve port types. While the difference is not difficult to distinguish, its effect on the mechanism is apparent.

What are valve bore sizes?

The valve port may also refer to the valve bore or the hole in the ball valve where the medium passes through. The valve port types depend on the size of the bore in relation to the pipe that it serves as a valve. Full port valves have the same diameter hole as the pipe, while standard port valves are actually one pipe size smaller in diameter than the pipe it connects.

Full Port Valve

A Full port valve or full bore valve is a valve that has the same bore size as the flow path that it connects or serves as a valve to. This means that the flow pressure remains constant as it passes through the valve and no flow resistance is experienced. Apart from the full bore ball valve, other types like the full port gate valve, full port plug valve, and full port globe valve, are often full bore valves because of the nature of their structure.

Reduced port valve

A reduced port valve, on the other hand, has a reduced-size port as its name suggests. The reduced bore ball valve dimensions are often smaller than 75% that of its original flow path.

Standard port valve

Standard Port

A standard port valve or regular port valve is similar to a reduced port valve but is only reduced 75%-90% than the original size. Much like the reduced port valve, a standard port ball valve and a standard port gate valve is available but are not as common as full port valves. They are preferred only if applicable because it is less expensive compared to full port valves.

Full port ball valve vs standard port

How to tell the differences?

Ball valves can either be a full port ball valve or a standard port ball valve. Full port ball valves maintain the same size diameter, while standard port ball valves have a reduced diameter size compared to the pipeline it serves as a valve to.

Ball Valve Full Port

A full port ball valve may be expensive and may require more space compared to standard ball valves but its advantage lies in the consistent flow pressure. Full port valves are ideal for pipes carrying liquids and solids because of their unobstructed nature.

Ball Valve Standard Port

A standard port ball valve is preferred for gaseous media, especially since it costs less and takes up lesser space than a full port ball valve. Standard port valves are a cost-effective option if pressure flow is not an issue.

ball valves standard port or bore type benefits

Standard port or bore valves are preferred for applications wherein there are space limitations. These valves are more compact compared to their full bore cousins, making them also require less materials and are therefore more cost-effective to produce and purchase. If the reduction of flow pressure is not an issue for the pipeline application, then standard port or bore ball valves are the practical and more space-saving choice.

Full port or full bore ball valve

Full port ball valves or full bore ball valves are basically ball valves that have a full bore or hole in the ball to allow for the passage of media through the valve to its connecting pipeline, such as 3 piece full port ball valve. These valves follow a straight path and an unrestricted flow. They have a larger body compared to a standard or a reduced port ball valve, as well as, a larger ball to accommodate a diameter that’s the same as the pipeline it connects. Little to no flow pressure loss is experienced when using a full bore or full port valve and no wear to the valve is added.

When to use full bore ball valve

full port ball valve for water heater

Full port ball valves are suited for applications like in a water heater since sediment or build-up can cause hot water to lose pressure. Build-ups and sediment are more common in standard port ball valves because of the reduction in diameter size and pressure loss when it passes through the valve.

Full port brass ball valves are especially durable because of the material used to make it. Brass itself has high resistance to corrosion and the structure of a full port ball valve further adds to its durability since full port ball valves are less prone to wear because of the consistent flow pressure that it undergoes.

A Stainless steel ball valve has additional properties that make it corrosion and abrasion-resistant. It performs well even under high pressure and temperature and requires less maintenance compared to other materials.

standard port valve

Standard port ball valves or standard bore ball valves are valves that have smaller diameter sizes compared to the pipeline that they connect or serve as a valve to. This makes them prone to the reduction of flow pressure and gives them a risk for cavitation.

When to use standard port or standard bore ball valve

Standard port or standard bore ball valves have the advantage of being cost-efficient and more adaptable to smaller spaces which is why they are a popular choice. They perform well in applications where pressure changes in the flow is no concern. If pressure flow is not an issue, a standard port or standard bore valve may prove advantageous because of its smaller size, lesser material, and reduced cost.

Full bore ball valves are considered to be high flow valves because of their ability to maintain flow rate and a consistent pressure.

Are There Other Valve Types Classified by Port Size?

While a gate valve and a globe valve typically do not have as extensive a classification as a ball valve, they do have different bore sizes depending on the application. Even though their bore sizes differ, gate valves and globe valves are essentially full bore or full port valves when they are fully open. Reduced bore designs are not usual but may be customized according to applications and to the standard.

Full port gate valve

Full port or bore gate valves have bore sizes that fit or conform to the size of the disc that is used to seal the valve. It is the usual design of gate valves and is more commonly produced and used.

Standard port gate valve

Image Source: Xhval

A standard port or bore gate valve or reduced port or bore gate valve is customized and must adhere to standards by the BSI and API. It is not as common as a full port or bore gate valve and not as widely produced, although manufacturers who customize valves may produce them according to the standards for the specific valve size.
