Product description

1. The double eccentric butterfly valve is a high-performance butterfly valve with an eccentric design for both the stem and disc. 2. The stem axis is offset from both the disc center and the valve body center. 3. This design allows the disc to quickly disengage from the seat during opening, reducing friction and wear, while achieving a tight seal during closing.

Value advantage

Safety and Reliability

In critical applications (e.g., chemical, power industries), the high performance and reliability of double eccentric butterfly valves help ensure safe system operation.
High Cost-Effectiveness

Although the initial investment in double eccentric butterfly valves may be higher than that of standard butterfly valves, their long service life and low maintenance costs result in high cost-effectiveness over their lifecycle.
Energy Saving and Consumption Reduction

The low fluid resistance design reduces system energy consumption, saving energy costs over long-term operation.
Bidirectional Sealing

Supports bidirectional sealing, providing flexible installation options and enhancing system flexibility and reliability.
Wide Applicability

Suitable for various media (e.g., water, steam, gas, corrosive liquids) and conditions (e.g., high temperature, high pressure, highly corrosive environments), offering strong versatility.
Compact Structure and Easy Installation

Its small size and lightweight design make it easy to install and maintain, reducing space requirements and installation costs.
Excellent Regulation Performance

Capable of wide-range flow regulation, it is suitable for systems requiring precise control, improving overall system efficiency.
Low Friction and Long Service Life

The disc quickly disengages from the seat during opening, reducing friction and wear, extending the valve's service life, and lowering maintenance costs.
High Sealing Performance

The double eccentric design ensures that the disc tightly fits the seat when closed, achieving zero leakage, making it particularly suitable for applications with high sealing requirements.
