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.

  • Product Details

New double eccentric butterfly valve represents the essence of an efficient butterfly valve designed for when economy is a high priority. ATHENA is functional and reliable, providing reduced complexity.
It covers the needs in standard applications for drinking water in terms of design, materials and standards. 

With a double eccentric structure, optimized disc design and robust sealing system, ATHENA valves provide reduced operating torque, minimized seat wear and reliable shut-off performance for demanding water and industrial applications.

key Feature:

  • Design and material selection are optimized for use in low and medium pressure drinking water applications.
  • Uninterrupted corrosion protection with pin-less connection and closed disc eyes ensure long service life and clean water.
  • Flow-efficient design for minimized head loss and low energy consumption significantly reduces the cost of ownership.
  • Double bearing kits to furthest reduce the torque, tansfer the weight of disc to body, also it could lock and fix the position of disc for long life using, even the valve could vertical downward direction.


Why Choose ATHENA Series ?


Dual Bearing System for Enhanced Shaft Stability

ATHENA Series adopts a dual bearing structure to support the disc and shaft assembly, effectively reducing operating friction and improving valve stability during long-term operation.

1. Reduced Shaft Deflection
The bearing system minimizes shaft movement under hydraulic load, ensuring stable sealing performance.

2. Extended Sealing Life
Multiple O-ring sealing protection prevents external contamination and protects internal sealing components during long-term service.

3. Improved Large Diameter Valve Performance
The dual bearing design is especially suitable for large diameter butterfly valves where disc weight and operating torque become critical factors.



Optimized Hydraulic Performance for Lower Energy Consumption

ATHENA Series adopts a dual bearing structure to support the disc and shaft assembly, effectively reducing operating friction and improving valve stability during long-term operation.


High Kv Value & Low Pressure Loss

The optimized disc profile provides higher Kv values and lower resistance coefficients, reducing pressure loss across the valve and helping optimize pump energy consumption.



Typical Applications:

Water Transmission Pipeline
Designed for municipal and regional water transmission systems requiring reliable isolation of large diameter pipelines.

Pump Station
Suitable for pump inlet and outlet isolation where reliable operation and low torque performance are required.

Water Treatment Plant
Applied in filtration systems, clear water pipelines and process isolation applications.

Industrial Cooling Water System
Provides reliable flow control for industrial water circulation and cooling applications.
