We are offering butterfly valve offset1 the shaft is offset behind the seat axis to allow complete sealing contact around the entire seat offset2 the shaft centerline is offset from the pipe and valve which provides interference free opening and closing of the valve offset3 the seat come axis is offset from the shaft centerline to eliminate friction during closing and opening and to achieve uniform compressive sealing arount the entire seat. Friction free sealing for long cycle life (1)seat is cr13 matal alloy or hardfaced with stellite as standard. (2)the gasket is spiral wound ss/graphite for zero leakage. (3)seat ring forces are generated by the torque during closing uniformly around the entire circumference.the resilent seal fleses and energizes, assuming the shape of the seat, the compression forces equally distributed around the perimeter provide a tight bi-directional shut off. The resiliency of the seal allows the valve body and disc to contract or expand, without the risk of jamming duo to temperature flunctuations.it is self-adjusting.
