What is api 608 valve?

API 608 valve is a type of safety valve. It is used in petrochemical, refineries, and power plants. API 608 ball valve is an essential part of the plant’s safety system. It is designed to limit pressure build-up, prevent loss of liquid or gaseous materials through the failure of piping, valves, or other components, or prevent damage if the plant is subjected to extreme pressures like earthquakes or explosions. The valves are installed at the entry point and remove excess pressure from the system when it’s not in use.

What is the most common application for an API 608 floating ball valve?

API 608 floating ball valve is used in pressures up to 300 bar and temperatures up to 260°C. They are commonly used in the oil and gas industry, chemical plants, refineries, water treatment plants, power generation plants, and other applications where high pressure and extreme temperatures are expected. The flow of liquids like crude oil, natural gas, crude oil, hot liquids, steam, etc. through pipelines, can be risky when the pipeline pressure is too high or low. If the flow is too high, the liquid may burst a pipe or overwhelm an API 608 valve and cause damage. On the other hand, if the flow is too low, the liquid may not bring in the required number of products and cause wastage. In this case, an API 608 floating ball valve is used to control the flow of liquids through pipelines.

How do you stop an API 608 trunnion ball valve leak?

When an API 608 trunnion ball valve leaks, it becomes difficult to close the valve. Therefore, it is necessary to stop the trunnion ball valve leak immediately. There are various ways to do it. One of the easiest and safest methods is to use a rubber plug. API 608 threaded ball valve can leak due to some jam inside the valve. You can unscrew and loosen the valve a bit, start the flow again, and then tighten the screws to see if the blockage has been left. If all attempts fail, it is best to replace the valve with a new one.

Does an API 608 threaded ball valve need to be fully open?

There are many types of valves that can be fully opened or fully closed. API 608 3 piece ball valves are one of those types. They are completely open during operation, i.e., when pressure is present in the system. However, during the time of shutoff, they are fully closed. This makes them suitable for controlling the flow of liquids and gases. In other words, it can be said that API 608 trunnion mounted ball valve is fully opened during operation and fully closed during shutoff.

Does the direction of API 608 3-piece ball valves matter?

Generally, API 608 metal ball valves are installed in the vertical direction, while gas valves are installed in the horizontal direction. But in API 608 valves, the operation direction doesn’t matter. All three parts of an API 608 3-piece ball valve can be installed and operated in any direction. While the flow direction is important, the design of the API 608 3 piece trunnion ball valves don’t require the valve to be unidirectional. They can operate to handle reverse directional flows as well. When these valves are operated in systems that require unidirectional flow, they are usually associated with check valves that facilitate the flow in only one direction.

What is the proper way to install an API 608 metal ball valve?

The proper way to install API 608 split body ball valves is in conjunction with a check valve and a piping system. A check valve is used to prevent the flow of liquids in one direction and gaseous materials in the other direction. Check valve types that can be used are gate valves, ball valves, and plug valves. The pipeline operations are shut down and the valve is fitted to the pipes in the desired position. They can be fitted either horizontally or vertically.
