Key Features
1. Excellent Sealing Performance: Hard seals achieve zero leakage, while soft seals provide even tighter sealing.
2. Wear-Free and Long Service Life: Opening and closing does not scrape the valve seat, making it more wear-resistant than ordinary ball valves.
3. Anti-Stuck and Self-Cleaning: The hemispherical rotation has a scraping effect, preventing mud, dust, and slurry from causing blockages.
4. Low Flow Resistance and Smooth Flow: The near-straight-through flow path reduces pressure drop, making it suitable for high flow rates.
5. Easy On/Off: The eccentric structure significantly reduces operating torque, suitable for both pneumatic and electric operation.
