Pneumatic Flange Type Butterfly Valve
•Characteristic
Because this butterfly valve adopt three-dimensional eccentric to design, make the movement track on facing space reach to idealization, and there are no attrition and on intervene between hermetical components, furthermore, the hermetical material has been selected reasonably, there by it ensure hermetic, 10 antisepsis, wearable capability of valve. The main characteristic as below:
1. Tiny moment for starting, flexible and convenient, save labor and energy.
2. Three-dimensional eccentric configuration forces disc close tighter, and reach to reliable hermetic capability and with no
leakage.
3. High temperature resistant, high pressure resistant, long service life etc.
