Data Center Liquid Cooling Primary Side High Performance Double Eccentric Butterfly Valve

Data Center Liquid Cooling Primary Side High Performance Double Eccentric Butterfly Valve

• High performance butterfly valve usually adopts single eccentric or double eccentric structure. The first eccentricity is that shaft deviates from centerine of sealing surface. The second eccentricity is that shalt deviates from centreline of the pipe. 
• Eccentricity aims to reduce the friction between the seal ring and seat after the valve opens to 20° .
• Soft seat which adopts TFE, PTFE and RTFE, also has good sealing when the fire occurs, because fireproof structure suits for the fire test according to API607.
• Metal Sealing structure has the entitative fireproof ability, it can assure the zero leakage of bidirection. Seat can be replaced when the shaft and the disc aren' dismantled. There's no low friction coefficient bush bearing at up and bottom shafts, so the friction is reduced when the valve is opening and closing.
• Double eccentric structure decreases the damage of secondary sealirg when the valve is opening or closing frequently 
• The interface of the valve and the driving mechanism is suitable for ISO5211,and the quality of product is controlled seriously according to ISO5211.
