Cast Steel Flange Butterfly Valve With Gear Worm

Features: 

The double eccentric butterfly valve is further improved on the basis of the single eccentric butterfly valve. Its structural feature is that the axis of the valve stem deviates from the center of the butterfly plate and the center of the body. The double eccentric effect enables the butterfly plate to be released from the valve seat immediately after the valve is opened, which greatly eliminates unnecessary excessive extrusion and scratching between the butterfly plate and the valve seat, reduces the opening resistance, reduces wear and improves The life of the valve seat is improved. The scraping is greatly reduced, and at the same time, the double eccentric butterfly valve can also use a metal seat, which improves the application of the butterfly valve in the high temperature field.

• Reasonable design, compact structure, easy assembly and disassembly, and easy maintenance.
• The eccentric structure is adopted to reduce the friction of the sealing ring and prolong the service life of the valve.
• Completely sealed, zero leakage. Can be used in ultra-high vacuum conditions
• Replace the valve plate sealing ring, butterfly plate, shaft and other materials, which can be applied to a variety of media and different temperatures
• Valve actuation choices: The valve can be equipped with electric actuator, pneumatic actuator or trigger handle and worm gear.
