Speciality Valve is esteemed as the prestigious Double Offset Butterfly Valve Manufacturers in India. Our commitment to superior service means that we support you throughout the entire process, from initial consultation to after-sales service and it is a type of valve widely used for controlling the flow of liquids and gases in various industrial applications.
How It Works
The Double Offset Butterfly Valve operates by using a rotating disc that moves perpendicularly to the flow of fluid. The two offsets in the design refer to the positioning of the valve stem and the centerline of the disc. The first offset is the displacement of the valve shaft from the centerline of the disc, and the second offset refers to the alignment of the shaft to the valve seat, creating a more efficient sealing mechanism.
The main components of a Double Offset Butterfly Valve are:
Valve Body: The outer casing that houses the internal components and provides the structure.
Disc: The rotating element that opens and closes to regulate the flow of fluid.
Stem: The shaft that connects the disc to the actuator or handle, transmitting movement.
Seat: A flexible ring that forms a seal between the valve body and the disc to prevent leaks when closed.
Actuator: The mechanism (manual, electric, or pneumatic) used to turn the valve stem and operate the disc.
Benefits of Double Offset Butterfly Valve
Improved Sealing Performance: The double offset design minimizes seat wear, which leads to better long-term sealing
Lower Operating Torque: The valve requires less torque to open and close, reducing the energy required to operate the valve
High Durability: The offset design helps to reduce mechanical stress and extend the lifespan of the valve.
Efficient Flow Control: Double offset butterfly valves provide excellent flow control capabilities, even at lower pressures.
Compact and Lightweight: Compared to other valve types, DOBVs are lightweight and require less space, making them ideal for installations where space is limited.
