In this section, we’ll cover 5 most common types of industrial valves: gate valves, globe valves, ball valves, butterfly valves and check valves as well as their respective advantages, disadvantages, and applications.
Gate valves are isolation valves and Control Valves designed to control the flow of liquid through pipes. As a linear motion valve, it’s commonly used in homes and commercial centers to start or stop the flow of water or other liquids. Gate valves are manufactured using different materials such as stainless steel, cast iron, alloy steel, and forged steel.
The functioning of gate valves involves lifting a circular or rectangular gate out of the fluid path. When the gate valves are open, there is no obstruction to the flow as the pipeline diameter and gate have the same opening. The valve size can be determined by its bore diameter.
Globe valves are widely used in various applications and are considered one of the most popular types of industrial valves. Similar to gate valves, they use linear motion to regulate the flow of fluid. These valves play a crucial role in controlling flow within pipelines by adjusting the position of a movable disk or plug in relation to a stationary ring seat. One notable advantage of globe valves is their ability to minimize leakage compared to other types of industrial valves.
The structure of globe valves consists of a baffle that divides the interior of the pipe, typically running parallel to its length. Their name is derived from the spherical shape of their body, which is separated into two halves by an internal baffle. Inside the valve, there is a movable disk-like element and a stationary ring seat, creating a generally spherical body.
As a type of control valves, ball valves are valves that use a ball to control the flow of substances from one opening to the next. Ball valves work by allowing the hole to be open, blocked, or open partially to regulate the flow of gas/liquid. Futhermore, ball valves are the ideal choice for using with gases as they are able to offer better sealing. They are very versatile as they support pressures up to 700 bars and temperatures up to 200°C and sizes typically range from 0.5 cm to 30 cm. They are easy to operate and repair as they contain a simple structure.
They are designed with special measures that permit only a 90-degree rotation which is required for the opening and closing of ball valves. These valves are a notable industrial choice because of their reliable and air-tight sealing when in the closed position.
• They contain a compact and low-maintenance design that requires no lubrication
• They are cost-effective among all of the other valves
• The biggest advantage of ball valves is that they have poor throttling characteristics that can cause the seat of a ball valve to easily erode.
• They provide leak-proof service.
• They open and close quickly.
• Ball valves have multi-way design flexibility.
• Ball valves are not suitable for permanent throttling.
• In residual fluids, the particles in the fluid collide with the surfaces and stick to them. This may cause leakage, abrasion, and other problems.
• Ball Valves are used for flow and pressure control and shut off for corrosive fluids, slurries, normal liquid and gases.
• They are used in the oil and natural gas industry, but also find a place in many manufacturing sectors, chemical storage, and even residential uses.
Butterfly valves are specifically designed to regulate the flow, although their control capabilities are somewhat limited. Operating a butterfly valve is as simple as rotating a handle 90 degrees. The valve features a metal disc positioned perpendicular to the flow when closed. By making intermediate rotations, the regulation of liquid flow can be achieved. Butterfly valves can be operated electronically, manually, or pneumatically, depending on the specific requirements.
These control valves find a wide range of applications in various industries such as water supply, wastewater treatment, fire protection, gas supply, chemicals, oil, fuel handling systems, power generation, and more. They can be operated using handles, gears, or actuators, offering flexibility based on the intended use.
Check Valves, also known as Non Return Valves (NRV), are essential components that allow the flow of liquid or gas in one direction while preventing backflow in the reverse direction. Their main purpose is to safeguard equipment and maintain the proper flow direction in a system.
These industry valves are commonly used to protect pumps in liquid applications and compressors in gas systems. By preventing backflow, they ensure the smooth operation of these devices and prevent potential damage or disruptions in the process. The design of check valves effectively reduces the occurrence of backflow in a pipeline.
One of the major advantage of check valves is their simplicity, allowing them to operate automatically without the need for human intervention or automation. They rely on the velocity of the fluid flow to open and close. As the flow rate increases, the valve opens further until it reaches its maximum, fully open position.
