Description The Type 8560 edisc high performance butterfly valves’ excellent shut-off capability is provided by the seal design. The valve includes filled-PTFE or graphite packing rings that electrically bonds the shaft to the valve body. This valve has a spline drive shaft end, and soft or metal seal rings for use in a wide variety of applications.
Installation The valve is normally shipped as part of a control valve assembly, with the power actuator mounted on the valve. If the valve or actuator have been purchased separately, or if the actuator has been removed for maintenance, mount the actuator on the valve, and adjust actuator travel before inserting the valve body into the line. This is necessary due to the measurements that must be made during the actuator calibration adjustment process. Refer to the Actuator Mounting section of this manual to mount the actuator on the valve. Refer to the actuator instruction manual for mounting and adjusting instructions before proceeding.
