Pipe Linkage Kit
Pipe linkage kits are available from Honeywell and can be used for linkage lengths from 24 to 240 inches (61 to 610 cm). The
kits include the mechanical pipe couplings, load rod end (left-hand thread), connecting rods and locking nuts. See Figure 4.
The actuator rod end (right-hand thread), nut and bolt are supplied with the actuator. The customer must supply a piece of
schedule 40 pipe 2 ½” * (both ends with right-hand NP threads) and a nut and bolt to connect the rod end to the load. Pipe
linkage kits can be ordered with the Actuator using Table VIII of the Model Selection Guide.
