F5 Sandwich Flow Controls
V-435BP
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 A) with
a 4 mm hex wrench.
2)
Clean all mating surfaces of valve, subbase or manifold and
Flow Control Sandwich of dust and dirt.
3)
Install three mounting studs (item C) to base, tighten to 2.9 to
3.8 N•m (25 to 35 in-lbs).
4)
Place the gasket (item D) that came with the Flow Control
Sandwich over the studs and on top of the subbase or manifold.
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 A) using a 4
mm hex wrench. Torque screws from 2.9 to 3.8 N•m (25 to 35 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 port 4)
controls flow from valve cylinder port 4 to exhaust, the screw to the
right (marked port 2) controls flow from valve cylinder port 2 to
exhaust. Both valves exhaust the base at port 3. Adjustment
technique:
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.
