An actuated butterfly valve is a type of quarter-turn valve that uses an actuator to control the flow of fluids or gases. The actuator can be electric, pneumatic, or hydraulic and automates the operation of the butterfly valve, providing precise and consistent flow control.
A lugged actuated butterfly valve has threaded inserts (lugs) on both sides, allowing it to be used in systems where downstream piping can be removed without affecting the upstream side. This feature makes maintenance easier and allows for dead-end service.
A wafer-style actuated butterfly valve is designed to fit between two flanges and is held in place by bolts that surround the valve body. This design is compact and lightweight, making it ideal for systems where space is limited.
A double flanged butterfly valve is commonly used in pipelines where a secure and rigid connection is required between two flanges. Its design allows for easy installation, reliable sealing, and safe handling of larger valve sizes in water treatment, HVAC, chemical, and industrial applications.
Actuated butterfly valves are commonly used in industries such as water treatment, chemical processing, oil and gas, power generation, food and beverage, and HVAC due to their reliable flow control and automation capabilities.
A bronze disc butterfly valve is chosen for its excellent resistance to seawater, brackish water, and other corrosive environments. The bronze material provides durability, prevents rapid corrosion, and makes it a reliable option for marine, desalination, and offshore applications where standard stainless steel may not perform as effectively.
Key benefits include automated flow control, compact design, cost-effectiveness, and versatility in handling various fluids. Their low-pressure drop and quarter-turn operation make them ideal for on/off and throttling applications.
To select the right size, consider the flow rate, pressure rating, and pipeline diameter. Ensure the valve's Cv (flow coefficient) aligns with your system's flow requirements, and consult manufacturer guidelines for accurate sizing.
Yes, actuated butterfly valves can handle high temperatures with the appropriate choice of materials. For instance, valves with stainless steel bodies and high-temperature seals (like PTFE or Viton) can withstand temperatures up to 400°C.
Yes, bronze disc butterfly valves can operate in higher temperature ranges compared to some plastic or rubber-lined alternatives. However, the exact temperature capability depends on the seat material and overall valve construction.
Yes, actuated butterfly valves are suitable for throttling applications due to their ability to control the flow precisely. However, ensure that the valve is designed and rated for throttling to prevent damage to the disc or seat.
Actuated butterfly valves should comply with standards such as API 609, ISO 5752, ASME B16.34, and AWWA C504. Additionally, valves used in food, pharmaceutical, or chemical industries may need to meet FDA or specific industry standards.
