Product Description

Eccentric Butterfly Valve. The valve utilizes a unique triple eccentric structure. Zero friction will emerge between the valve plate and the sealing ring. Triple-offset Butterfly Valves, shaft offset is created by designing the valve with the shaft located behind the centerline of the sealing surface (offset1) and slightly to one side of the pipe centerline (offset2). The third offset is the point of intersection of tangents of the seat and disc sealing deviating from the disc face. These offers are to completely eliminate all disc-to-seat friction throughout the valve's entire 90 degrees of rotation. Metal seal and laminated seat are optional. The triple offset provides ANSI Class IV, V, and VI leakage performance. The seat seal ring can be changed easily from the body.

Features:

1. Low operating torque. Triple Eccentric Butterfly Valves combine three offsets with flexible laminated metal and graphite to assure a tight and uniform seal and reduce operating torque.2. Anti-blowout Shaft. The double anti-blowout design satisfies API 609 and ASME B31.1 requirements through both internal and external stem retention. Top Retention: The packing gland follower retains the stem integral collar. Bottom Retention: T-shaped attachment prevents stem blow-out.

Benefits:

1. Zero Leakage. Laminated seal rings are designed to self-align and allow valves to meet zero leakage per API 598.2. Fire Safe Design. Triple Offset Butterfly Valves are not soft seated and can fulfill the fire-safe requirements of API 607.3. Low Emission Shaft Seal. We can supply low-emission stem seals with leakage rates of up to 20ppm per sniffing method with helium gas.
