Types of Butterfly Valves and Their Benefits

 

What is a Butterfly Valve?

A butterfly valve belongs to the quarter-turn valve family of valves. A quarter turn of the disc causes the valve to fully open or close. A metal disc mounted on a rod is the "butterfly." When the valve is closed, the disc is rotated to completely block the path. Once the valve is fully opened, the disc is rotated by a quarter turn to let the fluid flow virtually unhindered.

Types of Butterfly Valves

Hydraulic Counterweight Butterfly Valves:

Slow Closing Hydraulic Counterweight Butterfly Valve Control One class of advanced products used for controlling equipment management is the non-return butterfly valve, often known as the counterweight butterfly valve. They typically take the place of gate valves and check valves in irrigation, electric and water treatment pump exit areas, as well as in the area of the turbine entry in hydraulic power plants. 

Double Eccentric Butterfly Valves:

Double-eccentric butterfly valves are industrial valves. It is feasible to supply butterfly valves with surface protection, which is accomplished by covering them with plastic material. As a result of this surface protection and the usage of stainless steel material, the use of butterfly valves for media that are chemically hostile or abrasive as well as seawater is expanding.

Electric Butterfly Valve:

Electric Butterfly Valve actuated butterfly valves having a wafer body design for controlling the ON/OFF or placement of media suitable with the building materials, such as air, water, oil, and other media. Electric actuators have weatherproof casings, manual override, and electrical and visual valve position signalling.

Advantages of Butterfly Valve

One of the main factors favouring butterfly valves among companies and pipeline workers is its effectiveness. Butterfly valves are relatively easy to adjust and require minimal effort from staff because they offer a number of actuation options. The minimal weight and simple design of butterfly valves make them some of the easiest valves to maintain.

1. Cost-effective: Butterfly valves are generally more cost-effective than other types of valves, such as ball valves or gate valves. They are simpler in design, have fewer parts, and require less material to manufacture, resulting in lower costs.

2. Compact and lightweight: Butterfly valves have a compact and lightweight design, which makes them easy to install and suitable for applications where space is limited. Their reduced weight also makes them more cost-effective to transport.

3. Quick operation: Butterfly valves can be operated quickly, allowing for fast opening and closing. The disc inside the valve rotates a quarter-turn to open or close the flow completely, which is advantageous in applications where rapid shut-off is necessary.

4. Good flow control: Butterfly valves provide excellent flow control characteristics, allowing for efficient regulation of fluid or gas flow. They offer a high flow coefficient (Cv) and low-pressure drop, enabling smooth and unrestricted flow when fully open.

5. Tight shut-off: When closed, butterfly valves provide tight shut-off, minimizing leakage and preventing backflow. The resilient seat design ensures a tight seal, reducing the risk of fluid or gas escaping through the valve.

6. Low maintenance: Due to their simple design and fewer components, butterfly valves generally require less maintenance compared to other types of valves. They are less prone to wear and tear, and replacement parts are often readily available.

7. Versatility: Butterfly valves are versatile and suitable for a wide range of applications across various industries, including water treatment, HVAC, oil and gas, chemical processing, and more. They can handle large flow rates and are compatible with different types of media.

8. Good throttling capability: While butterfly valves are primarily used for on/off applications, they also offer moderate throttling capabilities. With the disc partially open, the flow can be regulated to achieve specific flow rates, making them suitable for certain control applications.

It's important to keep in mind that the appropriateness of butterfly valves depends on the particular requirements of the application. When choosing a valve type, variables including temperature, pressure, media composition, and system parameters should be taken into account.
