pneumatic butterfly valve

butterfly valve 1,Connection Form: Wafer 2,Work Pressure:Mid-Pressure (2.5mpa< Pn <6.4mpa) 3,Seal Form:Metal

butterfly valve:

HS Code:	8481804090
Connection Form:	Wafer
Work Pressure:	Mid-Pressure (2.5mpa< Pn <6.4mpa)
Seal Form:	Metal
Material of Seal Surface:	Metal
Structure:	Three-Eccentric Center Sealing

Because this butterfly valve adopt three-dimensional eccentrie to design, makes the movement track on facing space reachto idealization, and there are  no attrition and on intervene between hermetical components, furthermore, the hermetical material has been selected reasonably, thereby it ensure hermetic, Antisepsis, wearable caoability of valve. The main characterstic as below: 1. Tiny moment for starting, for starting, flexible and convenient, save labor and energy. 2. Three-dimensional eccentric comfiguration forces disc close tighter, and reach to reliable hermetic capability and with noleakage. 3. Lthascharacteristicof high temperature, high pressure resistant, antisepsis, wearable, long service life etc.
