Butterfly Check Valve Product Introduction
Product Overview:
The Butterfly Check Valve is designed to prevent backflow in pipeline systems. It features a butterfly-shaped disc that acts as a check mechanism. When the flow direction is correct, the disc opens and allows media to pass through. When the flow reverses, the disc closes to prevent backflow. This valve includes a hydraulic cylinder for slow closing. This mechanism helps to eliminate water hammer effects. The valve combines the functionality of a check valve with the compact design of a butterfly valve. It is widely used across various industries for its effectiveness and ease of use.
Structure and Features:
– Compact Design: The valve has a butterfly-shaped disc. This design makes the valve smaller and lighter than traditional check valves. It is ideal for installations where space is limited.
– Automatic Operation: The valve opens and closes automatically based on flow direction. No external power or manual intervention is needed.
– Slow Closing Mechanism: The valve is equipped with a hydraulic cylinder. This feature provides slow closing, reducing water hammer effects and minimizing shock to the pipeline system.
– Efficient Sealing: When closed, the disc creates a tight seal against the valve seat. This prevents backflow and maintains the integrity of the system.
– Durable Materials: The valve is made from high-quality materials such as stainless steel or ductile iron. These materials offer excellent resistance to corrosion and wear, ensuring a long service life.
– Low Pressure Loss: The streamlined design of the butterfly disc reduces pressure loss. This helps maintain efficient fluid flow.
Application Fields:
The Butterfly Check Valve is suitable for many applications, including:
– Water Supply Systems: It prevents backflow in water distribution systems. This protects pumps and other equipment.
– Wastewater Treatment: It ensures that wastewater does not flow back into treatment processes. This maintains system hygiene and efficiency.
– Industrial Processes: It is used in various industrial processes where backflow prevention is crucial. This ensures system performance.
– HVAC Systems: The valve controls the flow of air or water in heating, ventilation, and air conditioning systems.
Operating Conditions:
The valve performs well under standard pressure and temperature conditions:
– Maximum Pressure: It handles pressures up to 16 bar (1.6MPa). This is suitable for most industrial and municipal applications.
– Temperature Range: It operates effectively at temperatures up to 80°C. This makes it suitable for moderate-temperature environments.
– Size Range: Available in sizes from DN50 to DN600. This accommodates various pipeline diameters.
