Product Description

Offset Disc Butterfly Valve is an inline type flow control unit which is manufactured by using heavy engineering materials which imparts greater strength and rigidity to provide longer service life. It is fixed with a quarterly turn metallic disc fixed at the center which rotates about the vertical axis with the help of mechanical type lever to open or close the channel. The offered valve can be used in low to medium pressure flow systems.

Uses of Offset Disc Butterfly Valve:

1. Flow Control: Offset disc butterfly valves are used to precisely control the flow rate of fluids within a pipeline. They can be operated in a throttling mode to adjust the flow according to process requirements.

2. Isolation/Shut-off: These valves are often used as isolation valves to completely stop the flow of fluids in a pipeline. Their quick and easy operation makes them suitable for emergency shut-off applications.

3. High-Performance Applications: Offset disc butterfly valves can be used in high-performance applications, such as those involving high-pressure or high-temperature fluids. The design of these valves allows for better sealing performance under demanding conditions.

4. Water and Wastewater Treatment: These valves are commonly used in water treatment plants, sewage treatment facilities, and wastewater management systems to regulate the flow of water and various chemicals used in the treatment processes.

5. Chemical Processing: In the chemical industry, offset disc butterfly valves are utilized to control the flow of various chemicals, acids, and corrosive substances within pipelines.

6. Oil and Gas Industry: These valves find application in the oil and gas sector for controlling the flow of crude oil, natural gas, and various hydrocarbons in pipelines and processing facilities.

7. Power Generation: Offset disc butterfly valves are used in power plants to control the flow of steam, water, and other fluids within the steam generation and distribution systems.

8. HVAC Systems: In heating, ventilation, and air conditioning (HVAC) systems, offset disc butterfly valves are employed to regulate the flow of air, water, and other fluids in cooling and heating processes.

9. Food and Beverage Industry: These valves are used in the food and beverage industry for controlling the flow of various liquids, such as beverages, syrups, and food products, within processing and distribution systems.

10. Pulp and Paper Industry: Offset disc butterfly valves are utilized in pulp and paper mills to control the flow of pulp, chemicals, and water in various stages of the papermaking process.

11. Marine Applications: These valves are used in maritime applications to control the flow of seawater, ballast water, and other fluids on ships and offshore platforms.

12. Agriculture: Offset disc butterfly valves are used in agricultural irrigation systems to regulate the flow of water to fields, crops, and irrigation networks.


Q. What is an offset disc butterfly valve?

Ans: An offset disc butterfly valve is a type of quarter-turn valve that uses a disc with an offset pivot to control the flow of fluids through a pipeline. The offset design allows for improved sealing and reduced friction during operation.

Q. How does an offset disc butterfly valve work?

Ans: When the valve's handle or actuator is turned, the disc rotates on its offset axis, allowing the fluid to pass through or blocking the flow, depending on the position of the disc.

Q. What are the advantages of using offset disc butterfly valves?

Ans: Offset disc butterfly valves offer several advantages, including compact design, low pressure drop, quick operation, cost-effectiveness, and suitability for a wide range of fluids and applications.

Q. What are some common applications of offset disc butterfly valves?

Ans: These valves are used for flow control, isolation, and shut-off in industries such as water treatment, chemical processing, oil and gas, power generation, HVAC systems, food and beverage, and more.

Q. What materials are offset disc butterfly valves made from?

Ans: Valve materials can vary based on the application, but common materials include stainless steel, carbon steel, cast iron, and various types of elastomers for the valve seat and sealing elements.

Q. Are offset disc butterfly valves suitable for high-pressure applications?

Ans: Yes, offset disc butterfly valves can be used in high-pressure applications when designed and constructed appropriately. They are often chosen for their ability to handle higher pressures compared to other valve types.

Q. Can offset disc butterfly valves handle corrosive fluids?

Ans: Yes, they can. By selecting the right materials for the valve components, such as special alloys or coatings, offset disc butterfly valves can be designed to withstand corrosion from aggressive fluids.

Q. Are these valves suitable for both on/off and throttling control?

Ans: Yes, offset disc butterfly valves can be used for both on/off (full open or full shut) and throttling (partial opening) control of fluid flow.

Q. How do I choose the right size of offset disc butterfly valve for my application?

Ans: Valve size selection depends on factors like flow rate, pipe size, pressure, and application requirements. Consulting valve sizing charts and engineering guidelines can help determine the appropriate valve size.

Q. Are offset disc butterfly valves easy to maintain?

Ans: Yes, these valves are relatively easy to maintain due to their simple design. Regular inspection, lubrication, and replacement of worn-out parts can extend their lifespan and ensure optimal performance.

Q. Can offset disc butterfly valves be automated?

Ans: Yes, they can be automated by adding electric or pneumatic actuators. Automation allows for remote control and integration into process control systems.

Q. What's the difference between a concentric and an offset disc butterfly valve?

Ans: In a concentric butterfly valve, the disc pivot is centred, while in an offset disc butterfly valve, the pivot is situated away from the centre. Offset design provides improved sealing capabilities and better control in high-performance applications.
