SEQUENCE VALVE TEST (CONT)
(Sheet 2 of 4)
Plate like the one shown in the
Make with a thickness of .25 in. (6.3 mm).
Install in their correct locations in the valve
Plate, made in Step 1
Place in position on the bottom of the valve
so the .13 in. (3.2 mm) holes in the plate
align with the two bleed holes in the valve
body. Secure the plate to the valve with
bolts and nuts.
Get a supply source of pressure
For example, transmission test bench. Make
oil that can give 400 psi
sure the supply has a reservoir for leakage oil
(28.1 Kg/cm2) of pressure
from the valve.
Two 0 to 600 psi (0 to 42.4 Kg/
cm2) pressure gages, lines,
fittings and needle valve
Because the flow needed for this test is nor- See Sheet 3 for connection.
mally low, be sure the length of the lines
used is kept at a minimum so pressure differ-
nces (drops) are kept at a minimum.
