What conditions are valves commonly used in?

Valves are an extremely wide range of equipment that can be found almost anywhere. They are active under the streets, in houses, power plants and paper mills, refineries, and a wide variety of infrastructure and industrial facilities.

The seven industries commonly used and how they use valves:

Power industry Many power plants use petrochemical fuels and high-speed turbines to generate electricity.

Gate valves are preferred for on / off applications in power plants. Sometimes other valves, such as the Y-type cut-off valves, are also used. The use of high-performance ball valves is widely popular in the power industry.

Power plant applications put the pipes and valves under enormous pressure, so the valves require strong materials and designs to cope with the multiple tests of circulation, temperature, and pressure. In addition to the main steam valves, the power plant also has many auxiliary pipes. These auxiliary pipe consists of a wide variety of stop valves, butterfly valves, check valves, ball valves, and gate valves.

Water plant Water plants require relatively low pressure levels and ambient temperatures. 

Because the water temperature is room temperature, rubber seals and elastomers that are not suitable elsewhere can be used. These types of materials can be achieved by sealing the mounting of water valves to prevent water leakage. Valves in waterworks are usually much lower than 200 psi, so no high pressure and wall thickness pressure design is required. Unless valves need to be used at high pressure points in a dam or a long channel, a built-in water valve may be required to withstand around 300 psi.

Offshore industry The pipeline system for offshore production facilities and oil drilling platforms contains a large number of valves. 

These valve products have multiple specifications to handle all flow control problems. A key part of an oil production facility is the natural gas or oil recovery pipeline system. This system is not just used on the platform, its production system is usually used at depths of 10,000 feet or more.

The larger oil platforms require more processing of the crude oil from the wellhead. These treatments include the separation of gas from fluid vapor (natural gas) and the separation of water from hydrocarbons. These systems usually use ball and check valves as well as API 6D gate valves. API 6D Valves are not suitable for applications with strict requirements on pipelines, and are generally used in internal facility pipelines on drilling ships or platforms.

Waste water treatment Wastewater lines collect waste solids and fluids and leads them to the sewage treatment plant. 

Sewage treatment plants use low-pressure pipes and valves, and in many cases, wastewater valves are more more demanding than clean water requirements. Check valves and iron gates are the most popular options for wastewater treatment.

Oil and natural gas production Gas wells and oil wells and their production facilities use many heavy-duty valves.

Underground natural gas and oil have great pressure, and oil and gas can spray 100 meters high in the air. The combination of valves and special fittings exceeds 10,000 psi. This pressure is rare on land and is more common in deep-sea oil wells.

Valves used for wellhead equipment are subjected to high temperatures and extremely high pressure. Valve and pipe combinations usually contain special stop valves (called throttle valves) and gate valves. Special stop valves are used to regulate the flow rate from the well.

In addition to the wellhead, there are facilities requiring valves on natural gas and oil fields. These include process equipment for pretreating natural gas or oil. These valves are usually carbon steel and of lower grade.

Water pipeline Many important valves are used in these pipes: for example, emergency pipe stop valves.

The emergency valve may isolate a section of the pipe for maintenance or leakage. There are also scattered facilities along the pipeline: this is where the pipeline emerges from the ground, which is the equipment used to inspect and clean the production line. These stations contain multiple valves, which are usually ball valves or gate valves. The valves of the piping system must be fully opened to allow the sewer equipment through.

Commercial buildings Standing commercial buildings, with a lot of pipelines inside.

After all, every building needs water and electricity. For water, there must be various piping systems to transport tap water, waste water, hot water and fire prevention facilities.

In addition, in order to make the fire system work normally, they must have sufficient pressure, and the type and type of fire assembly valve must be approved by the corresponding management authority before installation.
