If you're an oil or gas engineer, you know that ball valves are very essential components of piping systems. They are used for various purposes throughout the oil and gas industry. For upstream applications, they control the flow of oil. For the midstream, they protect equipment by controlling the flow of gas and oil.Jun 19, 2019
Which valve is mostly used in process industries?
Double block and bleed valves are used primarily in process control applications for the purpose of shutting off the upstream pressure and bleeding off the fluid and/or pressure of the system. They may be manually operated or controlled by an electro-mechanical actuator.
How many types of valves are there in industry?
Industrial valves have been around for more than a century. As applications become more specific and complicated, valves have evolved into nine major types to suit different requirements. These 9 types cover all industrial applications and services. Valve categorization depends on several considerations.
What are industrial valves used for?
Industrial valves are mechanical devices that open, close, or partially obstruct passageways to regulate the flow of liquid or gas within a system.
Can a ball valve be used in a gas line?
Gas Ratings Only certain ball valves are approved for use with combustible gases, and these will have specific markings that explain where they can be used. Some of these include: Indoor Gas Ratings: ½ PSIG (PSIPSIG (PSIThe pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.https://en.wikipedia.org › wiki › Pound_per_square_inchPound per square inch - Wikipedia gauge): This low pressure rating is used for gas valves that are used in appliances.
Can you use a CWP valve for gas?
Cold working pressure (CWP) indicates the valve's maximum pressure rating at temperatures between -20°F to 100°F. ... It simply means that the valve is intended for use with water, oil or gas, with the exception of combustible gases.
Can I use a ball valve for propane?
These are compact CSA/CGA/AGA approved valves for Natural or Propane Gas, Mixed, and LP Liquefied Petroleum. They may also be used for air or water. These are compact CSA/CGA/AGA approved valves for low pressure Natural or Propane Gas, Mixed, and LP Liquefied Petroleum.
What type of valve is used for gas lines?
Globe valves A globe valve is a linear motion valve used to start, stop, and regulate flow. They help transport fuel oil, and they work in turbine lube oil systems and cooling water systems. Globe valves are some of the world's most common type of valve.Nov 25, 2020
What is a ball valves used for?
A ball valve is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked.
What is a ball style valve?
A ball valve is a form of quarter-turn valve that uses a pivoting ball that has been drilled through to control flow. When the hole is in line with the flow direction, it allows fluids or gasses to pass through. Alternatively, when the ball is turned 90 degrees, the flow is stopped completely.Apr 16, 2020
Where are valves commonly used?
Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on/off and pressure control to dish and clothes washers and taps in the home. Even aerosol spray cans have a tiny valve built in.
What are the advantages of a ball valve?
- They provide leak-proof service,
- Open and close quickly,
- Compared to gate valves, they have very small dimensions,
- Compared to gate valves, they are lighter,
- The multi designed flexibility does not exist in the Gate or Globe valve, and hence it lowers the amount of valves needed,
What is a inline valve?
Inline valves are probably the most common type of valve used in industrial automation systems; as their name suggests they fit directly in the individual line of each application. ... This, clearly, simplifies the pipework and centralises valves used for a particular process.
