Section IX – Internal Body Passages & Plug Locations
Two stage directional valves can be converted to different
operational modes, i.e., internal/external, pilot pressure or
drain, fast response, etc. To accomplish this, internal plugs
must be removed or added within the main stage body
passages.
Table 8 is a list of basic models with the incorporated
operational mode changes. Each model is referenced to a
particular figure. The figures illustrate internal passages and
plug locations.
Operational Mode Change
(Reference model code, Table 2)
* - Standard
X - Fast response option
E - External pilot pressure
CAUTION
DO NOT change internal plugs within main
stage body unless power is off and system
pressure is relieved.
K/R/S - Integral check valve
T - Internal pilot drain
