Butterfly Valve Manufacturer in Pune provides flow-control solutions for industries where liquids, gases, and process fluids need to be controlled, regulated, or isolated. Butterfly valves are widely used because they offer a compact design, simple operation, and practical flow-control performance.
Parth Valves and Hoses LLP offers butterfly valve solutions for pharmaceutical, food, chemical, water, and general industrial applications.
What Is a Butterfly Valve?
A butterfly valve is a quarter-turn valve used to start, stop, isolate, or control fluid flow through a pipeline. It uses a rotating disc inside the valve body to regulate the passage of fluid.
The selection of a butterfly valve depends on factors such as fluid type, pressure, temperature, pipeline size, material compatibility, connection type, and operating method.
Types of Butterfly Valves
Butterfly valves can be classified based on their end connection and disc/stem arrangement. Common options include wafer, lug, flanged, centric, double offset, and triple offset butterfly valves.
Wafer vs Lug vs Flanged Butterfly Valves
Wafer Butterfly Valve
A wafer butterfly valve is installed between two pipeline flanges. Its compact and lightweight design makes it suitable for applications where installation space is limited.
Wafer butterfly valves can be considered for water, food, chemical, pharmaceutical, and general industrial applications, depending on the valve material and process conditions.
Lug Butterfly Valve
A lug butterfly valve has threaded lugs around the valve body for connection to the pipeline. This design can be useful where individual pipeline sections need to be isolated during maintenance.
The appropriate body material, seat, pressure rating, and size should be selected according to the application.
Flanged Butterfly Valve
A flanged butterfly valve has integral flanges for connection with flanged pipelines. It can be suitable for industrial systems where a robust flanged connection is required.
These valves can be used in process pipelines, water systems, chemical applications, and other industrial fluid-handling systems.
Centric vs Double Offset vs Triple Offset Butterfly Valves
Centric Butterfly Valve
In a centric butterfly valve, the stem and disc are positioned centrally within the valve body. These valves are commonly used for general flow isolation and control applications.
Different body and seat materials can be selected according to the fluid and operating conditions.
Double Offset Butterfly Valve
A double offset butterfly valve has the stem positioned away from the centre of the disc and seat. This design reduces contact between the disc and seat during operation.
Double offset butterfly valves can be considered for demanding industrial applications where suitable sealing, durability, and reliable operation are required.
Triple Offset Butterfly Valve
A triple offset butterfly valve uses an additional offset in its seating geometry. This design supports a cam-like disc movement and metal-to-metal sealing arrangement.
Triple offset butterfly valves can be considered for demanding applications involving higher temperatures, pressures, or challenging process conditions.
Applications of Butterfly Valves
Butterfly valves are used across several industries for flow control and pipeline isolation, including:
- Pharmaceutical: Hygienic process and fluid handling
- Food & Beverage: Product transfer and pipeline control
- Chemical: Process fluid handling
- Water & Utilities: Water and utility pipelines
- Industrial: General process and fluid-handling applications
Valve material and seat selection should always be based on the fluid and operating conditions.
How to Choose the Right Butterfly Valve?
Before selecting a butterfly valve, consider:
- Type of fluid
- Operating temperature
- Working pressure
- Pipeline size
- Body material
- Seat material
- End connection
- Centric or offset design
- Manual or automated operation
- Chemical compatibility
- Hygiene requirements
For general applications, a centric butterfly valve may be suitable. For more demanding applications, double offset or triple offset butterfly valves may be considered according to temperature, pressure, sealing, and process requirements.
Similarly, wafer, lug, or flanged designs should be selected according to the pipeline configuration and installation requirements.

Frequently Asked Questions
What is a butterfly valve used for?
A butterfly valve is mainly used to start, stop, isolate, or control fluid flow in pipelines.
What is the difference between wafer, lug, and flanged butterfly valves?
Wafer valves fit between pipeline flanges, lug valves use threaded lugs for connection, and flanged butterfly valves have integral flanges for pipeline connection.
What is the difference between centric and offset butterfly valves?
A centric butterfly valve has a centrally positioned disc and stem, while offset butterfly valves use an offset design to reduce disc and seat contact during operation.
What is a double offset butterfly valve?
A double offset butterfly valve uses an offset disc and stem arrangement to reduce seat contact and support improved operation in demanding applications.
When is a triple offset butterfly valve used?
Triple offset butterfly valves can be considered for demanding applications involving higher temperatures, pressures, and specialized sealing requirements.
