In industrial valve technology, the butterfly valve has found a niche with its effectiveness, compactness, and adaptability. From humble beginnings in the mid-20th century to the smart, high-performance units available today, the butterfly valve has evolved a long way to meet the rising demands of industries worldwide. In this blog, we shall lead you through the fascinating history and the various types of butterfly valves, with particular reference to innovations introduced by V-Tork Controls, one of the leading butterfly valves manufacturers in India.

The Evolution of Butterfly Valves

Before butterfly valves and types of butterfly valves were invented, gate valves controlled on-off service and flow control by globe valves. Gate valves and globe valves were usually large, heavy, and needed a great deal of operating force. The 1940s were a valve design revolution with the advent of the butterfly valve, a light, strong, and low-cost device needing only a quarter-turn (90 degrees) for opening and closing.

Key Milestones in the Development of Butterfly Valves

• Pre-1900s: Gate and plug valves were predominant.
• Early 1900s: The idea of the rotating disc mechanism found in butterfly valves was taking shape.
• 1940s-50s: Rubber-seated butterfly valves were coming into play, which provided tighter seals and lower operating torque.
• 1960s-80s: Double-offset or high-performance butterfly valves were developed for industrial use.
• 1980s-90s: Triple-offset and fire-safe valves became available to meet higher specifications.
• 2000s-Present: Intelligent valves, integration of automation, utilization of exotic materials, and technology advances such as zero-leakage technology.

As a result, butterfly valves and types of butterfly valves have gradually substituted traditional valves across most industries, such as oil & gas, water, power, chemical, and food.

Understanding the Main Types of Butterfly Valves

When referring to butterfly valves types, they can be generally classified according to their type of design, level of performance, and mode of sealing. Let’s discuss the three major types of butterfly valves produced by V-Tork Controls, which is one of the top valve manufacturers in Coimbatore.

1. C-Series – Concentric Butterfly Valves

These are the most widely used types of butterfly valves manufactured by the Butterfly valves manufacturers and are also referred to as center-operated or center-centered. They are unique by the fact that the shaft remains at the center of the body and the disc. Disc is turned along the direction of flow, thus most ideal for simple flow control and shutdown.

Features

• Most ideal for water, air, and light chemicals.
• Manufactured for low-pressure applications (up to 25 bar).
• Have Wafer, Lug, and Double Flanged end connections available.
• Are cost-effective and reliable.
• Ideal for HVAC systems, water pipelines and light chemical applications.

Applications: Ideal for HVAC systems, water pipelines, and light chemical processing.
Being one amongst the reliable butterfly valve manufacturers, V-Tork Controls ensures high-quality rubber sealing for bubble-tight shutoff even in low-pressure applications.

2. 2X-Series – Double Offset High-Performance Butterfly Valves

This is an upgrade in the butterfly valves types spectrum. With two offset positions of the shaft, the valves minimize wear and friction for better functioning in mid to high pressure.

Features

• Conventional actuation flange.
• Low-emission and fire-safe design.
• Pressure-proof up to 50 bar and temperature-proof down to -29°C.
• Wafer, Lug, and Flanged End designs.

Applications: Petrochemical, marine, and oil & gas industries.
This butterfly valve is renowned for providing improved control, longer life, and fire-safe operation, which has earned it wide acceptability among valve manufacturers in India.

3. 3X-Series – Triple Offset High-Performance Butterfly Valves

This is the most sophisticated of the entire line of butterfly valve types, having been engineered with three offsets to reduce friction between disc and seat. These are zero-leakage, high-strength valves and are suitable for very low temperature and pressure operations.

Features

• Conical seat shape for a clean seal.
• Applicable for high-temperature uses and corrosive liquids.
• Engineered to have a long life with minimal maintenance.

Applications: Power plants, chemical processing, and steam systems.
These valve manufacturers ensure to deliver these valves with premium materials that comply with international standards.

Butterfly Valve Parts and Mechanism

Understanding butterfly valves parts is key to an understanding of how they are so simple and yet so effective. The principal components are:

• Body: Houses the valve internals.
• Disc: The portable component that controls flow.
• Seat: Enables close closure.
• Stem/Shaft: Couples the disc to the actuator.
• Actuator: Enables manual or automatic operation.

This simplicity not only minimizes maintenance requirements but also makes butterfly valves price inexpensive, particularly as against more massive types of valve such as globe or gate valves.

Related Valve Categories

Although butterfly valves are very versatile, there are situations where a different type of valve is required. For instance:

• Ball valve manufacturers ensure safe shut-off of gas and liquid piping.
• Knife gate valve manufacturers are best suited for wastewater and slurry systems because of their cutting action.
• Valve manufacturers in Coimbatore tend to provide a set of valves to serve various industrial requirements.

Final Note

From their invention in the 1940s to their current role in cutting-edge industrial systems, butterfly valves have revolutionized fluid control. Today, with options ranging from concentric to triple-offset designs, the type of butterfly valves you choose can drastically impact system efficiency, safety, and cost.
