Double-seated and discharge ball valves are designed to provide a reliable solution for isolation in critical applications. These valves feature two separate seat surfaces, allowing simultaneous flow shutdown at both ends, with an exhaust mechanism in the middle to ensure complete drainage and pressure relief.

Product Advantages

Compact design

Combining multiple valve functions into a single unit reduces space requirements and simplifies pipeline layout and installation processes.

Reduce maintenance costs

Fewer connection points can reduce the risk of leaks and system failures. Allow for quick inspections to minimize downtime to the greatest extent.

Operational Efficiency

Enhanced process control through a reliable shutdown feature. Facilitates system drainage and testing without the need for additional components.

Product Features

Dual blockage and bleeding mechanism

Two separate sealed elements provide primary and secondary isolation. The venting system allows for pressure relief and confirms a good seal.

A variety of materials

Available in stainless steel, carbon steel, and alloy materials to suit various environments. Corrosion-resistant, high-temperature, and extreme pressure resistance.

Multi-platform connectivity

Options include flanges, threaded, and焊接 ends for installation flexibility. Suitable for integration into various pipeline systems.

Fire safety and antistatic design

Design meets international fire safety standards. Anti-static function prevents discharge risks in hazardous environments.

Low operating torque

Effective design ensures smooth operation with minimal effort. Compatible with manual, pneumatic, or electric actuators, suitable for automation.
