YNTO UPVC Double-Eccentric Plastic Pneumatic Butterfly Valve 2 Inches to 12 Inches
The Double-Eccentric Plastic Pneumatic Butterfly Valve, compared to concentric butterfly valves, features a double-eccentric design that reduces the driving torque by 50%.
Product Introduction
The Double-Eccentric Plastic Pneumatic Butterfly Valve, compared to concentric butterfly valves, features a double-eccentric design that reduces the driving torque by 50%. All components in contact with the medium are made from the same pipeline material, minimizing the potential for leaks. The modular design of the butterfly valve system allows for easy and cost-effective changes to individual system components. It is applicable in water treatment, chemical engineering, biotechnology, shipping, food, and beverage industries.
Product Features
1. Double-eccentric sealing structure reduces wear; modular design.
2. The valve stem does not come into contact with the medium in the pipe.
3. Optimized disc shape results in low flow resistance coefficient.
4. Quick operation, with opening and closing time < 2 seconds for fast on/off.
5. Actuator connection conforms to ISO5211 standards.
6. Actuator with NAMUR standard interface.
7. Enhanced sealing performance for greater reliability.
8. Effectively absorbs water hammer impact.
9. Low operating torque allows for rapid opening and closing.
10. Longer service life; can achieve automatic control by adding accessories.
11. Impurities and particles do not accumulate on the disc; compatible with multiple standard flanges for easy installation.
