Throughout Check Valves – Tilting Disc and Butterfly Types
Check valves play a crucial role in controlling the flow of fluids in piping systems, preventing backflow and ensuring efficient operation. Among the different types of check valves available, tilting disc and butterfly check valves are widely used throughout various industries. By understanding their design, functionality, applications, and benefits, you can make informed decisions about incorporating these valves into your fluid handling systems.
Understanding Tilting Disc Check Valves
Tilting disc check valves are designed to allow fluid flow in one direction while preventing backflow. They consist of a disc that tilts on a hinge or pivot mechanism, allowing the disc to lift off the seat when fluid flows in the desired direction. When reverse flow occurs, the disc returns to its closed position, sealing against the seat and preventing fluid from flowing backward.
These valves offer several advantages, including:
• Fast Closure: Tilting disc check valve provide rapid closure due to the disc’s design and the absence of springs or other closing mechanisms. This ensures quick response and minimizes the risk of water hammer.
• Low Pressure Drop: The streamlined design of the disc and the absence of obstructions in the flow path result in minimal pressure drop across the valve, allowing for efficient fluid flow.
• Durability: Tilting disc check valves are known for their robust construction and materials, providing reliability and long service life even in demanding applications.
• Versatility: These valves are suitable for a wide range of fluids, including liquids, gases, and slurries. They find applications in industries such as water supply, wastewater treatment, chemical processing, and oil and gas.
Understanding Butterfly Check Valves
Butterfly check valves, also referred to as swing check valves, are another type of throughout check valve. They consist of a disc that swings on a hinge or pivot mechanism to allow fluid flow in one direction while preventing backflow. When reverse flow occurs, the disc swings back into a closed position, sealing against the seat and blocking the flow.
Butterfly check valves offer several advantages, including:
• Compact Design: Butterfly check valves feature a compact and lightweight design, making them suitable for applications where space is limited.
• Low Pressure Drop: The streamlined disc design and minimal obstruction in the flow path result in low pressure drop, enabling efficient fluid flow and energy savings.
• Quick Response: Butterfly check valves offer fast response and closure due to the swinging disc design, minimizing the risk of water hammer and system damage.
• Versatility: These valves are suitable for a wide range of applications in industries such as water treatment, HVAC systems, irrigation, and fire protection. They can handle various fluids, including water, air, and compatible gases.
