Triple Eccentric Butterfly Valve
Triple Eccentric Design for Tight Sealing with Low Torque
Disc disengages from the seat quickly when opening and ensures tight peripheral sealing upon closing — achieving bidirectional zero leakage with significantly reduced torque.
Multi-layer Metal Seal for Harsh Conditions
Engineered with multi-level metal sealing rings to ensure reliable performance in high-temperature, high-pressure, and corrosive environments.
High Flow Capacity with Low Pressure Loss
Streamlined flow path provides low resistance and high flow coefficient (Cv), approximately three times that of conventional valves of the same size.
Self-cleaning Operation for Extended Lifespan
Non-friction opening/closing minimizes seat wear and enables self-cleaning, contributing to long-term reliability.
Actuator-ready for Flexible Automation
Compatible with standard pneumatic or electric actuators, enabling seamless integration with automated control systems.

A municipal water supply project in a certain area of Africa
- Africa
Customer/Owner: Ministry of Water Resources
- Working conditions/Challenges:
From 2018 to 2020, we provided valves, ductile iron pipe fittings to the Arusha Sustainable Urban Water Supply and Sanitation Delivery Project in Africa for three consecutive years, helping local residents improve their living conditions.
- The type of equipment adopted:
During this period, we provided electric triple eccentric butterfly valves with diameters of DN400, DN700, DN900 and DN1200 for the project, and equipped them with AUMA actuators. Currently, the project has been successfully delivered.
