When the primary decisions are made, valve selection is usually an afterthought. But there are numerous types of valves: ball valves, butterfly or wafer valves, globe valves, check valves and diaphragm valves. A piping system may contain many different types of valves, depending on their purpose.

Valve controls, however, are crucial for the successful operation of any system. Additionally, valves deserve much greater attention when considering material options, since the strength of any system depends on its weakest component or joint.

What are valves

An opening, a closing, or a partial obstruction of fluid flow is a valve because it regulates, controls, or directs fluid flow. Does that make sense? Sure, let's simplify it a bit.  Controlling the pressure and flow of fluid within a process is done with valves. Therefore, it controls pressure and flow.

The valve is a mechanical device that regulates the flow of fluid through a pipe by partially or completely obstructing it. To brush your teeth, you turn on the faucet (tap), which opens a valve allowing pressurized water to escape.

Gases and liquids can be controlled by valves. For example- in a gas cooktop (hob) for your stove, the controls that regulate the temperature and pressure of the gas are valves. Increasing the heat opens up a valve that allows more gas to enter the pipe. As more gas is burned, the flame gets bigger, so you get more heat.

Machines that use liquids or gases are pretty much guaranteed to have valves. Each time you rinse out your clothes washer, the water supply is turned on or off by a valve in the machine. Additionally, the combustion chambers of your car have valves that constantly open and close to admit air and fuel and release exhaust gases burned during the combustion process.

So, you see, valves are not only used in industries but also in our daily lives.

Function of valves

• Controlling the flow of a fluid. The process fluid can pass through or be stopped according to the state of the valve.

• Limiting the flow of fluid. You can throttle the fluid with some valves based on the amount of fluid flowing through them. A smaller opening results in a higher throttling and vice versa.

• Directing the flow of a fluid. Multiport valves are used to direct the flow of a fluid.

• In a piping system, regulating a flow or pressure is necessary. Automatic control valves adjust the opening and closing of valves within the system to maintain flow and pressure.

• Relieve the equipment and piping system from pressure or vacuum. In vacuum or overpressurized conditions, pressure relief valves prevent damage to the processing system.

1. Pipelines

There are hundreds of miles of pipelines that carry media from its source to its destination, where it is transformed into its final product. This use is essential to many industries. Both onshore and offshore crude oil and gas piping can be included in this media.

These valves are found upstream, midstream, and downstream in the pipeline and are used to optimize the operating conditions. Upstream is a section of the pipeline starting at the bottom of the wellhead and ending at the choke. Wellheads have specialized globe valves known as chokes, which regulate the output of the well. The midstream takes place between the choke and the final destination (typically a refinery). Downstream consists of everything inside the destination's area.

In choosing a pipeline valve, it is important to consider whether the valve can be piggable, which means that it can be cleaned or inspected from the inside.

If your industry manufactures hydrogen peroxide, you surely need to contact activated alumina balls manufacturers for the proper functioning of your production system.

2. Oil and Gas

A subset of the pipelines category is the oil and gas industry. Higher oil and gas demand has resulted in the need for longer pipelines, deeper wells, and lower production costs. A valve must both be inexpensive and tough so the industry can meet their demands, as well as last longer and perform better.

The environmental conditions and operating conditions of valves are often very extreme, with temperatures exceeding 1,500°F and pressures exceeding 25,000 PSIG, as well as cryogenic and very low-pressure applications. Oil and gas valves should also have the capability of being remotely controlled.

3. Food and Beverage

Food and beverage plants are large and growing industries, which have an increasing need for products and parts to keep them running. As a result of many challenges the industry faces, including safety concerns, valves used in these plants must conform to strict material standards.

The food and beverage industry classifies valves into two groups: those directly in contact with food and those that handle utility services (water and steam). There are regulations (issued by organizations like the FDA) stating that valves that come into direct contact with food should be smooth enough so that particles or bacteria cannot accumulate inside the valve.

Soft materials should not be used for valves, which absorb or hold the product that is going through them. Additionally, the standards specify that there must not be a dead volume in any crevices or valves where material could stagnate or decay. There are no high pressures or highly corrosive materials in the food and beverage industry.

Conclusion

Valves are one of the most important components in an industry so choosing the best ones should be your priority as an industry owner. If you want certified valves, you should contact the best oil and gas valve manufacturers in the world.

To prevent any electrical hazards too, you should invest in the best high voltage vacuum contactor from a reputable manufacturer.
