High Performance Butterfly Valve
FEATURES
• High performance butterfly valves usually adopt double eccentricity and a special oblique cone elliptical sealing structure. This design solves the problem of the sealing surface of traditional eccentric butterfly valves still being in sliding contact friction at the moment of opening and closing 0∘∼10∘, achieving the effect of separation of the sealing surface of the butterfly plate at the moment of opening and sealing at the moment of closing contact, thereby extending the service life and improving the sealing performance.
• Double eccentric design makes the butterfly plate and the sealing surface separate quickly, reducing friction, high frequency and long service life.
• G-type valve seat with automatic compensation design keeps reliable sealing.
• Oil-free self-lubricating bushing.
• Unique packing for dynamic load compensation seal design eliminates the valve Leakage.
• Anti-frying design prevents the valve stem from being damaged and blown out.
• Anti-static design.
