Key Features of Centerline Butterfly Valves
Compact Design:
Lightweight and space-saving, making them ideal for applications with limited space.
Quarter-Turn Operation:
The valve can be fully opened or closed with a 90-degree turn of the handle or actuator.
Centerline Disc Alignment:
The disc is aligned along the centerline of the valve body, ensuring smooth operation and reduced wear.
Bidirectional Flow:
Can control flow in both directions, making them versatile for various applications.
Materials:
Available in a variety of materials, including stainless steel, cast iron, and plastic, to suit different media and environments.
Sealing Options:
Equipped with soft seals (e.g., EPDM, Viton) or metal seals for tight shut-off and compatibility with different fluids.
Actuation Options:
Can be operated manually (lever, gear, or handwheel) or automatically (electric, pneumatic, or hydraulic actuators).
Types of Centerline Butterfly Valves
Wafer Type:
Designed to fit between two pipe flanges, held in place by bolts. Ideal for low-pressure applications.
Lug Type:
Has threaded inserts (lugs) that allow the valve to be bolted directly to the pipeline flanges. Suitable for end-of-line service or dead-end applications.
Flanged Type:
Comes with flanges that match the pipeline flanges, providing a secure connection. Commonly used in high-pressure applications.
Double Flanged Type:
Features flanges on both ends, making it suitable for high-pressure and large-diameter pipelines.
Applications of Centerline Butterfly Valves
Water Treatment:
Used in water distribution, filtration, and wastewater treatment systems.
HVAC Systems:
Regulates the flow of water or air in heating, ventilation, and air conditioning systems.
Chemical Processing:
Controls the flow of corrosive or abrasive fluids in chemical plants.
Food and Beverage:
Used in sanitary applications to handle liquids like milk, juice, and beer.
Oil and Gas:
Manages the flow of oil, gas, and other hydrocarbons in pipelines.
Pharmaceuticals:
Ensures precise flow control in sterile and hygienic environments.
Advantages of Centerline Butterfly Valves
Cost-Effective:
Lower initial cost and maintenance compared to other valve types.
Lightweight and Compact:
Easy to install and requires less space than gate or globe valves.
Quick Operation:
Can be opened or closed quickly with a 90-degree turn.
Low Pressure Drop:
Provides minimal resistance to flow when fully open.
Versatility:
Suitable for a wide range of applications, including liquids, gases, and slurries.
Durability:
Resistant to wear and corrosion, especially in valves made from stainless steel or other high-quality materials.
Components of Centerline Butterfly Valves
Body:
The outer casing that houses the internal components and connects to the pipeline.
Disc:
The rotating component that controls the flow of fluid. It is aligned along the centerline of the valve body.
Stem:
Connects the disc to the actuator or handle, allowing the disc to rotate.
Seat:
The sealing surface that ensures tight shut-off when the valve is closed.
Actuator:
The mechanism used to operate the valve (manual or automatic).
Gasket:
Provides a seal between the valve body and the pipeline flanges.
How Centerline Butterfly Valves Work
Open Position:
The disc is rotated 90 degrees to align with the flow, allowing fluid to pass through with minimal resistance.
Closed Position:
The disc is rotated perpendicular to the flow, blocking the passage of fluid and creating a tight seal.
Throttling:
The disc can be positioned at intermediate angles to regulate the flow rate.
