1. The valve is designed as angular travel ball valve structure, connection by BW flange.

2. The valve trim and seat material is high temperature alloy + stellite

3. The valve internal leakage could reach grade VI and zero external leakage.

4. Imported single action angular travel piston type pneumatic actuator was applied.

5. The opening and closing period of valve less than three seconds.

6. The valve with side-mounted hand wheel for easy operation at site, the changeover of manual and pneumatic is easily.
