A butterfly valve is a quarter-turn rotational motion valve, used to stop, regulate, and start flow. Butterfly valves are beneficial when you need a compact design with quick operation that requires less time to open or close. Ramén Valves offer butterfly valves that are made in Sweden for shut-off or simple regulation of corrosive gases and liquids. They are available in a wide range of high alloys and titanium.

How does a butterfly valve operate?
Butterfly valves operate by turning the disc either parallel or perpendicular to the flow direction. When the disc is parallel to the flow, the valve is open, allowing fluid to pass through. When the disc is perpendicular to the flow, the valve is closed, blocking the flow.
The opening angle of the damper blade is controlled by hand lever or gear, or by a pneumatic or electric actuator.
Advantages of the butterfly valve
Quick Operation: Butterfly valves require only a quarter turn to go from fully closed to fully open, making them faster to operate than some other types of valves.
Compact Design: Their simple design and compact size make them well-suited for applications with limited space.
Low Pressure Drop: When fully open, butterfly valves offer minimal obstruction to flow, resulting in lower pressure drop across the valve.
Cost-Effective: Butterfly valves are often more cost-effective than other valve types, making them a popular choice for various applications.
Butterfly valves are commonly used in various industries, including water treatment, HVAC systems, chemical processing, power generation, food and beverage, and more. They are suitable for both large-scale industrial applications and smaller commercial systems.
