Main Features:

1. Double eccentric design and forced sealing: Small opening and closing torque, small sealing pair abrasiveness extends valve service life.

2. Single-seat, full-bore design: No pressure loss when fully open; when closing, no medium retention in valve cavity. Stellite-alloy welded on the sealing pair has high hardness and high abrasiveness resistance.

3. Self-cleaning function.

4. Floating seat design: Floating valve seat can absorb thermal expansion.

5. Fixed valve ball design: Valve stem only bears rotary torque to ensure that the valve stem will not be stuck in extreme cases.

6. Range of working temperature: 0℃~425℃.

7. Medium: Clean water, sewage, sea water, acid and alkali liquids, slurry, steam, oil, containing granular medium.

8. Application: Petroleum and petrochemical, metallurgy, chemical industry, electric power, gas, water conservancy, municipal administration, and construction industries.
