ELECTRICAL DATA
APPLICATION DATA
Flow Actuating Pattern
Operating actuator “A” opens flow
path to port “A” (P→A). Operating
actuator “B” opens flow path to port
“B” (P→B). Models with Code 6
operators, which are actuator
centered, are the exception.
Spring-centered or spring-offset
models are spring positioned unless
actuated continuously. Valves with
detented operation can be actuated
momentarily (minimum electrical
signal duration, 50 ms) to shift and
hold the spool in that position.
Mounting Position
Unrestricted for all models.
Standard Seals
All valves use fluorocarbon (Viton
®
or
Fluorel
®
) o-rings, providing greater
fluid compatibility and improved
temperature range performance.
Fluid Recommendations
50 to 1500 SUS (7 to 323 cSt) viscosity;
-20° to 200° F (-29° to 93° C)
temperature range.
Filtration
Five micron or better is recommended
for this high pressure valve.
MANUAL OPERATED MODELS
Lever operated models offer handle
position flexibility with four positions
on either port “A” end or port “B” end
of valve.
In-the-field changes are easy, by
removing the bracket assembly and
rotating the handle to the desired
position.
To specify position, see the instal-
lation drawing on page 7 and refer to
“Typical Model Code” on page 8.
Fine filtration is especially critical for
sliding spool valves held in one
position for long periods, subjected
to high system pressures. Silting
may cause spool sticking and
improper shifting. To further prevent
this occurrence, valves should be
cycled periodically.
Differential Cylinder Circuits
High differential flows in cylinder
circuits can cause any hydraulic valve
to malfunction. Contact the Dynex
sales department for a review of appli-
cations with differential flows (P→A
versus B→T, or P→B versus A→T)
above 6.6 gpm (25 L/min).
Pressure Surges
Consistent with standard practice,
the system should be protected from
pressure surges. With a common
tank line serving multiple valves,
shifting of any spool valve can be
affected by surges of oil.
A separate line to tank, or to another
low pressure line, is recommended.
This is particularly critical with
detented models.
