In piping systems, valves are considered to be the workhorse. From ball and globe valves used in the power industry to butterfly valves used in pharmaceutical processing to gate valves used in oil and gas production, industrial valves perform countless jobs from isolating to regulating flow in many different industries. The differences between valves are what makes them unique – ball valves help regulate flow, check valves prevent backflow, and gate valves handle high temperatures and pressures. Among the most common types of valves are ball, butterfly, check, gate, and globe valves. We are the leading industrial valve exporters.
What is Ball Valves?
Ball valves are compact, cost-effective, and low-maintenance quarter-turn valves. A ball with a hole is inside the valve. The hole in the ball allows media to pass through when the valve is open. A quick 90-degree turn of the handle on top opens and closes the valve. One of the simplest valves to operate is a ball valve because of its effortless turn.

Flow and pressure are typically controlled with ball valves. As a leak-proof and easy-to-operate valve, ball valves are often used in the oil and gas industries; however, they are also found in the manufacturing and chemical storage sectors, as well as in residential settings.
Explanation of Industrial Butterfly Valves
As with ball valves, butterfly valves are quarter-turn valves. In butterfly valves, the handle is attached to a stem, which is attached to a disc inside the valve. The disc inside rotates to open and close when the handle is turned. Throttling can also be done with butterfly valves since the disc sits inside the valve.
You may experience a pressure drop if the disc sits inside the valve since the disc is always inside. There are many applications for butterfly valves, including water supply and wastewater treatment. Large-diameter pipes are also commonly fitted with butterfly valves.
Check Valves: What Are They?
A check valve has one major advantage over other valves on this list: it is self-automated. Flow passes through check valves in one direction and backflow is automatically prevented. Pressure from the flow opens the disc inside, so the higher the pressure, the more it opens.
The disc inside will close when the flow decreases or reverses. The term Non-Return Valves (NRV) refers to checking valves since they prevent backflow. Since they automatically prevent backflow, they are an excellent choice for protecting pump and compressor lines from backflow.
Gate Valves and Their Common Industrial Uses
In isolation applications, gate valves belong to the shut-off/on the family. As the top handle is turned, the gate inside slowly rises and lowers. As the gate is completely out of the flow path when fully open, there is no resistance. Gate valves should only be used for starting or stopping the flow, not for throttling as this can damage the disc. Various media can be passed through gate valves, including air, liquid, and steam. Water main shutoff valves and wastewater gate valves are some of the most common applications for gate valves.
The globe valve is one of the most popular types of the valve because it can be used to stop, start, and regulate flow. An internal baffle separates the two halves of a globe valve, which is spherical. Typically, the baffle runs parallel to the pipe. It is less likely for globe valves to leak than other valves because of their excellent shutting mechanism.
As a result of their ability to stop, start, and regulate flow, globe valves are widely used in a variety of applications. It is common to see them used as regulators for fuel oil systems, boilers, main steam vents, drains, and cooling water systems.
Choosing the Right Valve for a Pipeline System
What is the purpose of the valve you are looking for? This is the most important question to ask yourself when looking for a valve. A pipeline system would not be complete without valves. It doesn’t matter what demands your system has, there is a valve that can handle them. Gate valves are used for isolating flow or regulating flow with butterfly valves.
The valve is a specific opening or closing mechanical control element, which regulates or directs the flow of fluids, gases, or electricity. The valve is also referred to as a gate, as it controls the flow of fluid through a pipe, tube, or conduit. The valves are designed to allow for the fluid to flow freely for a short period of time, usually, until the valve is tripped, which is a mechanism used to rapidly open or close the valve. The valve is the most important part of the piping system, as it is used to direct the flow of the fluid. Aira Euro Automation Pvt ltd is one of the top-rated industrial valve exporters.
