What is The Difference Between a Ball Valve and a Butterfly Valve?

Both ball valves and butterfly valves are rotary valves that turn 90 degrees from fully open to fully closed. Most types of gases or liquids can be controlled by both of these valves at a wide range of temperatures and pressures. There are two types of valves that are popular for their relatively low cost, long service life, and dependability: butterfly valves and ball valves. There are, however, a few differences to help the user decide which to choose. Let’s learn about them and their pros and cons first. We are the leading butterfly valve in Zambia. 

Ball Valves

As the name suggests, Ball Valves use a ball to control the flow of elements from one end to another. Their versatility and better sealing make them a great choice. The only difference between a ball valve and a butterfly valve is the shape of the rotating plugs. The ball valve is spherical and has a hole drilled in it. Due to their reliable and air-tight sealing when closed, these valves are highly demanded in the industrial sector.

Advantages of Ball Valves:

  • It is possible to operate ball valves without side loads
  • Low maintenance costs
  • It opens and closes quickly
  • Makes certain there are no leaks
  • Low purchase and maintenance costs are associated with this valve
  • The service life of ball valves is long
  • High pressure and high-temperature flow can be handled by this device
  • Lubrication is not required for ball valves
  • Leak-proof service is provided by ball valves

Disadvantages of Ball Valves:

It is difficult to clean ball valves, and an improper cleaning process can cause contamination

There is a poor throttling characteristic with this valve

Permanent throttling is not possible with ball valves

Butterfly Valves

An example of a butterfly valve is a simple piping system that has a rotating disc that rotates across the flow. Butterfly valves regulate flow with limited control capabilities. Butterfly valves operate manually or automatically by rotating the handle at 90 degrees. The closed position of the valve consists of a metal disc positioned perpendicular to the flow. Handles, gears, or actuators can use to operate these valves. 

Aira Euro Automation is the leading butterfly valve in Zambia. We offer various types of industrial valves like ball valves, butterfly valves, control valves, pressure reducing valves, globe valves, gate valves, and many more. 

Butterfly Valve

Advantages of Butterfly Valves:

  • There is very little maintenance requir this valve.
  • A butterfly valve has a low-pressure drop and a high-pressure recovery
  • Media that is chemically or corrosively reactive can use
  • There is an open port on this valve
  • Butterfly valves are compact and lightweight
  • This valve is available in a larger size
  • High Flow Efficiency 
  • The accuracy of butterfly valves is excellent
  • Throttles flow when necessary.
  • It is possible to install or remove butterfly valves without dislocating the pipe system.

Disadvantages of Butterfly Valves:

  • Butterfly valves are difficult to clean, and they also take a lot of time to clean
  • Butterfly valves restrict to low-pressure throttling
  • Turbulence affects disc movement
  • There is no tight shut-off on butterfly valves

Common Characteristics Between Ball Valves and Butterfly Valves

A number of characteristics shar between Ball Valves and Butterfly Valves, including

  • They are both relatively inexpensive, long-lasting, and dependable.
  • A Valve Distributor can easily provide both types of valves, which are the most common.
  • These valves are made from brass, cast iron, and stainless steel.
  • Ball Valves and Butterfly Valves are both quarter-turn rotary valves, which require a 90-degree turn to open and close.
  • A valve can regulate the flow of most types of gas and liquid at a wide range of temperatures.

Difference Between a Ball Valve and Butterfly Valve

It is clear that we are aware of these two valves, but let us understand their differences since they both perform unique functions

  • Ball valves provide a reliable seal, whereas butterfly valves do not seal since they rarely use control gas flow.
  • A butterfly valve uses a disc to open and close, while a ball valve uses a ball. Discs and balls rotate at 90 degrees around their axes. Unlike ball valves, butterfly valves can adjust quickly, whereas ball valves take time to adjust
  • A butterfly valve operat manually, whereas a ball valve operat both automatically and manually.
  • In general, butterfly valves are less expensive and lighter than other types of valves. Butterfly valves for large diameter pipes are much smaller than ball valves.
