Butterfly Valves | Types, Diagram, Price & Applications
Butterfly Valves: Types, Diagrams, Price, and Industrial Applications | AIP Valves
Butterfly valves are one of the most widely used industrial flow control valves due to their compact design, fast operation, and cost-effectiveness. From HVAC systems and water treatment plants to fire suppression systems and industrial piping, butterfly valves are valued for their reliable shutoff and flow control.
At AIP Valves, we manufacture and supply high-quality butterfly valves designed for durability, leak-proof performance, and consistent operation in demanding applications while supporting IGBC-aligned, sustainable building practices
This guide covers everything you need to know about butterfly valves: types, operation, diagrams, price, actuator options, symbols, HSN codes, and industrial applications.
What is a butterfly valve?
A butterfly valve is a quarter-turn rotary valve used to regulate or isolate fluid flow in a pipeline. It consists of a circular disc mounted on a shaft that rotates inside the valve body. When the disc turns parallel to the flow, the valve opens; when rotated perpendicular, the valve closes.
Because of their lightweight construction and space-saving design, butterfly valves are preferred over bulky gate and globe valves in medium to large-diameter pipelines.
Butterfly Valve Operating Principle
The operating principle of a butterfly valve is simple and efficient:
- The disc rotates 90 degrees to control flow.
- Fully open → minimum pressure drop
- Fully closed → tight seal
- Partially open → flow regulation
- This makes butterfly valves ideal for applications requiring fast operation and frequent cycles.
Butterfly valve diagram
A typical butterfly valve diagram includes:
- Valve body
- Disc
- Stem
- Seat or seal
- Actuator (manual or automatic)
Diagrams help engineers and designers understand installation position, flow direction and actuation method, especially during system design and implementation.

This valve is recommended for applications where standard butterfly valves do not offer sufficient leak-tightness or durability.
Types of Butterfly Valve Actuator
Butterfly valves can be operated manually or automatically depending on system requirements.
- Manual Operated
- Lever operated (small sizes)
- Gear operated (larger sizes)
2. Electric Butterfly Valve Actuator
- Precise flow control
- Remote operation
- Ideal for HVAC and automated systems
Choosing the right butterfly valve actuator ensures efficiency and long service life.
Butterfly Valve Symbol
In piping and instrumentation diagrams (P&ID), the butterfly valve symbol represents a compact shut-off valve used in fluid control systems. Understanding valve symbols is essential for consultants, designers, and project engineers during layout planning and execution.
Butterfly Valve HSN Code & GST
The butterfly valve HSN code is commonly used for taxation and invoicing purposes in India.
- HSN Code: 8481
- Applicable GST rate depends on usage and classification
Correct HSN classification ensures smooth billing, compliance, and logistics for industrial projects.
Butterfly Valve Price in India
The price of a butterfly valve varies depending on several factors:
- Valve size (DN / NB)
- Type – Standard or High-Performance
- Body, disc, and seat material
- Pressure rating (PN10, PN16, ANSI)
- Actuator type (manual or electric)
Instead of choosing purely on price, it is important to consider performance, sealing reliability, and life cycle cost.
