The need for this Valve
Valves play a vital role to control the flow of any fluid such as water, oil, and gas. However, each substance has its unique kind of valves to automate that has full control of its flow. There are different kinds of pipes available in the market today concerning operating system to regulate the flow rate of any type of fluid in a pipeline. Let’s discuss the importance of globe valves which got its name due to spherical in design that works under heavy load which consists of movable disk-type element and a stationary ring seat. This valve is also best known as linear motion valve and is different from the ball valve. It is primarily used to shut off, start, and regulate the flow by moving the disc against the flow stream. Hence it is conventionally used for isolation and throttling services in the gas and oil industry. The internal mechanism of this valve mainly consists of body, bonnet, stem, plug or disc, cage, and seat. Recently it got recognition as the world’s most common types of valves that are used across the globe to ease the mechanism of oil and gas flow in the market.
The primary purpose of this valve in the field of oil and gas industry:
It serves as an essential tool that eases the task of engineers for the free flow of oil and gas through pipelines and helps them to regulate the process of isolation and throttling services. It thus acts as a conventional method that is helpful to have full control on flow pattern and change the direction when required otherwise result in a high-pressure drop.
The most important feature of this valve is its seating arrangement that is parallel to the line of flow. All you have to do is rotate the handwheel that is adjustable to any desired level to control the rate of flow of fluids. It is thus most efficient throttling commodity that can be used for yielding minimal disk and seat erosion. Due to this configuration, one can even experience a large amount of resistance within the valve.
They are mainly used to ease the process in cooling water systems, turbine lube oil and fuel oil systems, steam, air, gas, and other corrosive fluids vents and drains as it is helpful to increase and decrease the flow pattern of fluids via spinning its handwheel.
This valve is available mainly in 3 types based on its disc arrangement. The most common disk designs often in use are ball type, composite type, and needle type. Even though it is more substantial than other valves but its operation is simple as it is easy to repair due to its seat and disk that are accessible from the top of the faucet itself.
Leverage the design of this valve that is very convenient to use, especially when the flow of the commodity needs to change its direction within the valve itself. Hence it is highly beneficial to use when the flow resistance and pressure drop need to be monitored and accordingly the change in direction concerning pressure drop and turbulence. This shutoff capability got named it as a stop-check valve.
