How do I assemble valve sections?
Inlet Section:
First, make sure that the machined mounting surfaces of the sections, the section washers and o-rings are clean of
contaminates. Next, install three (3) split washers, two (2) mounting brackets and 9/16” [14.3mm] nuts to the tie rods.
Follow this by installing the three (3) tie rods into the mating holes in the Inlet valve section with mounting brackets on
bottom and facing outward. At this point, the washers, mounting brackets and nuts on the tie rods should be facing away
from the flat, machined surface on the Inlet section.
Work Sections:
Now, add the first Work section of your stack valve. Begin by installing three (3) thin (shim washers) which came with the
work section, on to the tie rods. Slide these shims all the way up against the machined side of the Inlet section. Next, make
sure that work section o-rings are clean and free of contamination and installed into the work section. Finally, slide the entire
work section with the o-rings facing the machined side of the Inlet section all the way down the tie rods. Repeat for the
remaining work sections.
Outlet Sections:
Finally, install the Outlet section following the same procedure as the Work sections. Install the remaining split washers,
nuts, and mounting bracket (handle side), then hand tighten 9/16” [14.3mm] nuts.
Finish assembling the valve by tightening the tie rod nuts to the correct toque setting: see “What is the correct torque for the
tie rod nuts?” previous page. Be sure the mounting feet are flat against the table while the nuts are tightened to the torque
setting.
