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.

Koei actuators are engineered for long service life with minimal wear, while carbon steel valve bodies offer rugged durability. This combination means fewer unexpected breakdowns, easy manual override during servicing, and reduced overall maintenance costs in continuous process operations.

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.

Koei actuators are known for their precision and durability, which pairs perfectly with the robust nature of carbon steel butterfly valves. Together, they provide reliable flow control in demanding industrial environments, handling both high-pressure and high-cycle operations with ease.

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 – carbon steel offers excellent mechanical strength, while Koei actuators are built with weather-resistant housings and stove enamel finishes for added protection. This combination makes them ideal for applications such as oil & gas, power plants, and heavy industry where exposure to the elements is common.

Absolutely. Depending on the process requirements, Koei actuated carbon steel butterfly valves can be configured with different seat and disc materials, fail-safe actuator options (spring return or double acting), and accessories such as limit switches or positioners for precise control.

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.
