Symbol
NOTE:Sandwich flow controls can only be used with F3 valves
manufactured after 3/1/97 (date code CB3). These units
will have socket head cap screws for holding the valve
body to the base. Sandwich units will not fit units with
button head screws.
Installation of Flow Control Sandwich
(For valve installation see the instruction sheet(s) shipped with the
product)
1)
Remove the valve from the subbase or manifold (if assembled)
by loosening the three main body mounting screws (item #1)
with a 3 mm hex wrench.
2)
Clean all mating surfaces of valve, subbase or manifold and
Flow Control Sandwich of dust and dirt.
3)
Apply a light coating of grease (in kit) to gasket (item #2) and
place in gasket track on bottom of Flow Control Sandwich.
4)
Install three mounting studs (item #3) to base, turning finger
tight and then backing off so the flats of the studs are parallel to
side of base.
5)
Place Flow Control Sandwich on top of subbase or manifold,
lining up all three mounting studs. Electrically operated
valves also require lining up electrical plug with socket in base
and gently pressing down on Flow Control Sandwich to seat
plug properly.
6)
Check to insure that the gasket on the bottom of the valve
sandwich block is still properly seated in its gasket track. Then
place valve assembly on top of flow control. Line up electrical
plug with socket in flow control and gently press down on valve
to seat plug properly.
7)
Tighten the three captive mounting screws (item #1) using
a 3 mm hex wrench. Torque screws from 2.5 to 2.9 N•m
(22 to 26 in-lbs) using progressive steps with a criss-cross pattern.
8)
Apply inlet pressure and check for leaks. If any are present,
do not operate the valve - repeat this assembly process
until satisfactory.
Adjustment Procedures
Both adjusting screws are located at the 12 end of the assembly.
When viewed from this end, the screw to the left (marked 4-3)
controls flow from valve cylinder port #4 to exhaust, the screw to the
right (marked 2-3) controls flow from valve cylinder port #2 to exhaust.
1)
Turn both adjustment screws clockwise until fully closed and
then counterclockwise slightly.
2)
While cycling cylinder with valve turn adjusting screws
counterclockwise to increase exhaust flow or clockwise to
decrease exhaust flow.
