Different types of valves and their pros and cons

Valves are a helpful component in all plumbing aspects. In addition to controlling flow and pressure, they permit a complete stop or flow of fluids inside a pipe. To vary the flow’s direction or even divide it into many directions, numerous valves are also employed.

Based on their function, there are many types of valves offered by the best valve exporters in India. Each type has its advantages and disadvantages. Let us study these types and their pros and cons in detail.

  1. Butterfly valves

Butterfly valves offered by industrial valves exporters, use a quarter-turn of the internal rotating disc mechanism to fully open or close the valve. The butterfly-like picture that butterfly valves produce while they are operating to control flow is how they receive their name.

Pros –

  • Butterfly valves are built from a limited set of components. As a result, the layout is straightforward.
  • Butterfly valves can move mud when there is a small liquid deposit in the pipe’s output.
  • The installation charges are minimal

Cons –

  • Butterfly valves lack strong shutoffs.
  • Even when fully opened, some of the discs are constantly exposed to the flow.
  • There’s a chance of cavitation and choking
  1. Check valves

Instrumentation Valves Exporters in Mumbai deal with Check valves that only allows liquid to flow in one direction and stop media from flowing backwards. Check valves are used to stop the system’s process flow from reversing, which could harm equipment or disrupt the process.

Pros –

  • Check valves result in less downtime.
  • Check valves protect machinery like pumps and compressors from harm caused by backflow.
  • Control valves offer minimal maintenance costs since they have smaller movable elements.

Cons –

  • It might be problematic when a valve disc becomes stuck in the open position.
  • The installation arrangements for check valves are subject to some restrictions.
  1. Globe valve

A baffle, which is normally parallel to the length of the pipe, separates the interior of the pipe to form a globe valve. Their spherical bodies, which feature an internal baffle dividing the two halves, gave rise to their name. It has a usually spherical body with a moving disk-like element and a fixed ring seat.

Pros –

  • Because there is just one sealing surface, globe valves are relatively simple to maintain.
  • Globe valves experience less wear and tear than other valves do.
  • They have positive shut-offs and can be used as stop-check valves.

Cons –

  • They have a large disc assembly opening.
  • In comparison to a ball valve, the opening speed is slower.
  • They have a low flow coefficient.

Use and Advantage of Different Types of Valves

Valves used in plumbing and other related works are manufactured in various parts of India. Such Valves Manufacturers in India make many different types of valves. In this article, we discuss the different types of valves made by Industrial Valves manufacturers and their advantages and disadvantages.

  1. Gated valves

A gate valve is made by many Valves Manufacturers in Mumbai. These types of valves move a gate vertically and are used to open or close the pipeline completely. There are no small openings possible. The entire gate is either closed or opened. If you are looking for a regulated flow, a gate valve wouldn’t be an ideal choice.

  • Advantage: They have very less fluid resistance. The force required to open/ close is comparatively small.
  • Disadvantage: Large space is required for installations. The two sealing faces make processing, grinding, and maintenance tough. The time taken to open/ close is also more.
  1. Butterfly valve

If you need a valve that can open and close often, a butterfly valve would be a good choice. Purchase them from the Best Valves Manufacturers in Mumbai to enjoy good quality and performance.

  • Advantage: They have a simple structure and weigh less. The time taken to open and close is small. They resist fluid in minute amounts. They can be used for different media surfaces and are widely made by Instrumentation Valves Manufacturers in Mumbai.
  • Disadvantage: The range of adjustments available for flow is narrow. It cannot be used in high temperatures or pressure conditions in a piping system. Sealing quality is inferior in comparison, hence not preferred much.
  1. Globe valve

A globe valve is highly recommended in cases where regulation of flow is needed. The opening and closing create friction which is less than other valves made by Instrumentation Valves Manufacturers in India. So, the chances of wear and tear are much less in this case.

  • Advantage: Maintenance and repair of the valve are quite simple, as it has only one sealing surface. The valve is resistant to higher temperatures.
  • Disadvantage: The change in flow direction is subject to change and causes more resistance to flow. The opening of the valve is slow in comparison.
  1. Ball valve

A ball valve is an advanced form of plug valve with a ball-shaped opening and closing device. We rotate the ball to 90 degrees whenever it needs to be closed or opened. Industrial Valves manufacturers in Mumbai make these useful valves.

  • Advantage: A ball valve is reliable when dealing with corrosive media and can achieve full sealing even when temperature and pressure are high. The sealing surface is not easily eroded.
  • Disadvantage: Industrial Valves manufacturers in India use Teflon to make ball valves. These have poor thermal conductivity. We cannot adjust it much either.

Final Overview McNeil is one of the Best Valves Manufacturers in India with several years of experience in the field. They provide good quality valves for industrial use in all types and materials. The number of satisfied customers is testimony enough of their product quality.

IMPORTANCE OF INDUSTRIAL VALVES

Every process setup is created using different kinds of machinery, equipment, and devices. One such element used in a process setup is ‘Valves’. Valves are a fundamental component in all process setups and there can be no flow system setup without them.

WHAT ARE INDUSTRIAL VALVES

A valve is a mechanical device that regulates, controls, or directs the flow of liquid, gases, fluidized solids, or slurries in a piping system. It helps in controlling the flow by opening, blocking, or partially obstructing passageways. Industrial valves are used to handle high-pressure and are designed to last in harsh environments. The main function of industrial valves is to control, isolate, or divert the flow of liquids, and gases through pipes.

There are different kinds of valves with different physical properties, structures, and applications. Let us see some commonly used valves across all process industries.

BALL VALVES TO THROTTLE FLOW

Ball valves are flow control devices with rotating, perforated, hollow balls that regulate the flow of fluid through pipes. Ball valves are generally suitable for low-flow applications and are widely used to throttle gases and vapors in hydrocarbon processing systems. It needs only a quarter turn to turn on/off the flow. The process engineering needs generally define the size of the ball valve required to regulate the flow.

CHECK VALVES TO PREVENT BACKFLOW

Check valves are two-port industrial devices with two openings, one for fluid to flow into and the other for fluid to flow out. They rely on internal pressure for opening and closing, rather than outside action. The main function of a check valve is to prevent backflow; hence it is also called a non-return valve. Check valves are mostly applied in compressed air and gas systems and vacuum pumps. The check valves manufactured by McNeil Instruments help in reducing head loss of water. Know more now.

GATE VALVES FOR MINIMUM RESTRICTION IN FLOW

Gate valves are valves with discs that are gate or wedge-shaped and have a linear movement. This allows easy and effective shut-off/on mechanism. It removes barriers from the liquid’s path of travel. Therefore, it is used to either entirely start the flow or completely stop the flow of fluid. It can be used in bi-directional flow and where a minimum restriction is required. Few industries where gate valves are commonly used are Oil and Gas, manufacturing, automotive, and pharmaceuticals.

NEEDLE VALVES FOR LOW FLOW RATE IN EXTENDED PERIOD

A needle valve is a valve with a small port and a threaded needle-shaped plunger. Needle valves are often used in flow-metering applications, especially where a constant, low-flow rate is required for a long period, such as idle fuel flow in a carburettor.
