Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.
Valves are the most common equipment in chemical companies. It seems easy to install valves, but if they are not implemented in accordance with the re...
The manual valve is a valve operated by the handle and the hand wheel, and is a commonly used valve on the equipment pipeline.

MINOTAUR series replaceable seat high performance butterfly valve
The ATHENA Double Eccentric Butterfly Valve is engineered for demanding water transmission and distribution systems where reliable sealing, low torque operation and long-term durability are essential.
Designed according to EN593 and EN1074 standards, ATHENA valves are widely suitable for municipal water networks, pumping stations, treatment plants and large diameter pipeline projects.
Compared with concentric butterfly valves, the double eccentric design reduces seat friction during operation, resulting in longer seat life and smoother opening / closing performance.

Why Double Eccentric Design Matters
Unlike concentric butterfly valves, the shaft in a double eccentric valve is offset from the disc centerline and seat centerline.
This design helps:
For large diameter water pipelines, these advantages often translate into lower lifecycle cost.
Installation Recommendations
For best field performance:
For buried or flood-prone chambers, IP68 gearbox configuration is recommended.
