What Are Valves?
First, let’s start with the basics. Valves are devices that regulate, direct or control the flow of fluids (liquids, gases, or slurries). They do this in several ways.
They either help with opening, closing or partially obstructing passageways. While they play a part in medical scenes, the valves we’re discussing today are for commercial applications.
Valves are essential in oil and gas, water treatment, food and beverage processing, power generation, and more. But not all valves are equal, so choose carefully. Overall, if you purchase your valves from a reputable company like Everlasting Valve Company, things will run smoothly.
Caring for Valves
Be sure to care for your valves properly. Is your project environment eroding, cavitating or fast flow? Valves in high-pressure and/or high-temperature conditions require certain features to avoid damage.
For example, valves meant for high pressure need thicker materials to withstand the force, while those handling extreme temperatures require heat-resistant materials to not lose strength or sustain other types of damage.
Also, by keeping materials away from the valve surfaces, you can avoid damage to the valve. Hard materials are also helpful in preventing damage to the valve.
Metering Valves
When it comes to metering valves, there are a few things that you need to know in order to make sure that you’re using them correctly. Metering valves control the flow of liquids or gases. They control the flow through a pipe or other conduit (here are some important tips about conduit fillings).
Metering valves are usually used in applications where precise control over the flow rate is necessary. For instance, this happens in manufacturing or laboratory settings.
Metering valves come in a variety of different designs, each of which is better suited for different applications. The most common type of metering valve is the ball valve, which uses a ball-shaped plug to control the flow of liquid or gas.
When choosing a metering valve, it is important to consider the specific application that you will be using it for. Different types of metering valves are better suited for different applications, so it is important to choose the right one for your needs. If you are not sure which type of metering valve is best for your application, you should consult with a professional who can help you choose the right valve for your needs.
Ball Valves
Ball valves are another common type of valve used in industrial applications. Ball valves get their name from the ball-shaped component inside the valve that controls the flow of fluid.
The ball has a hole in the center that allows fluid to flow through when the valve is open and blocks the flow of fluid when the valve is closed. Ball valves are durable and easy to operate, making them a good choice for many applications.
Like other types of valves, ball valves are available in a variety of materials to suit the needs of different applications. Common materials for ball valves are brass, stainless steel, and carbon steel. Ball valves can also be made from other materials, such as plastic and bronze.
When choosing a ball valve for an application, it is important to consider the pressure and temperature rating of the valve as well as the material it is made from. The pressure and temperature rating will determine the maximum amount of pressure and temperature that the valve can safely handle.
The material the valve is made from will determine what fluids it can be used with. For example, brass ball valves can be used with water, air, and some chemicals, but they are not suitable for use with oils or other fluids that could corrode the brass.
Ball Valve Varieties
Ball valves are available in a variety of sizes, from small valves that are only a few inches in diameter to large valves that are several feet in diameter. The size of the valve will determine the flow rate that it can handle.
Smaller ball valves are typically used for applications where a low flow rate is sufficient, such as in residential plumbing. Larger ball valves are required for applications where a higher flow rate is needed, such as in industrial settings.
Operating Tips
Ball valves can be operated manually or automatically. Manual ball valves require the user to turn a handle to open and close the valve.
Automatic ball valves are controlled by an electric or pneumatic actuator. Automatic ball valves are typically used in applications where the valve needs to be opened and closed frequently, such as in an industrial process.
Check Valves
Check valves are used to prevent backflow in a system. They allow fluid to flow in one direction only, and they open and close automatically. When fluid flows in the direction of the arrow on the check valve, it opens and allows fluid to pass through.
When fluid tries to flow in the opposite direction, the check valve closes and prevents backflow. Check valves are widely used in systems where backflow must be prevented.
Pinch Valves
Pinch valves are a type of valve that is used to control the flow of fluid by pinching or squeezing a flexible tube that carries the fluid. Pinch valves are often used in applications where precise control over the flow of fluid is needed, such as in medical applications. These valves can be opened and closed manually or automatically.
Butterfly Valves
Butterfly valves are a type of valve that gets its name from the butterfly-shaped disc inside the valve that controls the flow of fluid. The disc is connected to a stem, which is turned to open and close the valve.
When the stem is turned so that the disc is parallel to the flow of fluid, the valve is open, and fluid can flow through. When the stem is turned so that the disc is perpendicular to the flow of fluid, the valve is closed, and fluid cannot flow through. Butterfly valves are commonly used in applications where a large amount of fluid needs to be controlled, such as in water pipelines.
Gate Valves
Gate valves are a type of valve that gets its name from the gate-like component inside the valve that controls the flow of fluid. The gate is attached to a handle, which is used to open and close the valve.
When the handle is turned so that the gate is parallel to the flow of fluid, the valve is open, and fluid can flow through. When the handle is turned so that the gate is perpendicular to the flow of fluid, the valve is closed, and fluid cannot flow through. Gate valves are commonly used in applications where a large amount of fluid needs to be controlled, such as in water pipelines.
Gate valves are classified as either rising stem or non-rising stem valves. Solid wedge gate valves have a solid piece of metal that forms the wedge between the seat and the disk, while flexible wedge gate valves have a flexible piece of metal, such as a rubber gasket, that forms the wedge between the seat and the disk.
Gate Valve Advantages
There are several advantages to using gate valves. First, they are very durable and can withstand high pressures. Second, they provide a tight seal when closed, which prevents leaks.
Third, they are relatively easy to operate. Finally, they are available in a wide range of sizes to accommodate different applications.
Gate Valve Disadvantages
There are also some disadvantages to using gate valves. First, they are not suitable for applications where precise control of fluid flow is required. Second, because the gate moves up and down to open and close the valve, it can become corroded over time and may need to be replaced more frequently than other types of valves. Third, when opened, gate valves can cause water hammer, which is a sudden increase in pressure that can damage pipes.
Globe Valves
Globe valves are a type of valve that gets its name from the globe-shaped component inside the valve that controls the flow of fluid. The globe has a hole in the center that allows fluid to flow through when the valve is open and blocks the flow of fluid when the valve is closed. Globe valves are often used in applications where precise control over the flow of fluid is needed, such as in chemical plants.
There are two main types of globe valves: the first type has a stem that goes through the center of the globe, and the second type has a stem that goes around the outside of the globe.
The type of stem that a globe valve has will determine how the valve is operated. Globe valves with a stem that goes through the center of the globe are operated by turning the stem to open or close the valve.
Globe valves with a stem that goes around the outside of the globe are operated by pushing or pulling on the stem to open or close the valve. Globe valves are also made from a variety of materials, such as cast iron, brass, bronze, stainless steel, and plastic.
Solenoid Valves
Solenoid valves are a type of valve that is controlled by an electromagnet. The electromagnet activates when electricity is applied, which opens the valve and allows fluid to flow through. Solenoid valves are often used in applications where automation is needed, such as in manufacturing plants.
Another thing about solenoid valves is that they can be used for on/off control. When the solenoid is activated, the valve opens and allows fluid to flow through.
When the solenoid is deactivated, the valve closes and stops the flow of fluid. This makes solenoid valves a good choice for applications where on/off control is needed, such as in water treatment plants.
Solenoid Valve Materials
Solenoid valves can be made from a variety of materials, such as brass, stainless steel, or plastic. The material you choose should be based on the environment in which the valve will be used. For example, if the valve will be used in a corrosive environment, then a stainless steel solenoid valve would be a good choice.
There are 2 main solenoid valves you can use. They’re either direct acting or pilot operated.
Direct-acting solenoid valves have a simple design and are typically less expensive than pilot-operated solenoid valves. Pilot-operated solenoid valves, on the other hand, have a more complex design but offer greater control over the flow of fluid. Consult a professional if you’re unsure which one will serve you best.
