* Ambient temperatures below freezing require moisture-free
air. Ambient temperatures below freezing and above 180°F
require lubricants especially selected for suitability at these
temperatures.Pneumatic valves should be used with filtered
and lubricated air.

Installation & Operating Instructions:
Flow Control Valves are designed to provide an adjustable
restriction for varying or metering fluid flow in one direction
through the valve and Full Flow in the opposite direction through
the same valve.
For most double acting cylinder applications, two Flow Control
Valves should be used. This makes possible accurate and
independent control of cylinder piston speed in both stroke
directions. It is generally best to install Flow Control Valves in
the pipe lines between the Cylinder and Directional Control
Valve, as close to ports on the Cylinder as piping will permit.
Air flows through valve with minimum restrictions in direction
of arrow printed on label. Flow in opposite direction is metered,
depending on setting of Metering Needle.
Valve may be used for either Meter-In Control of air flow TO
Cylinder Port or Meter-Out Control of air flow FROM Cylinder
Port. For Meter-Out Control, install valve with Full Flow arrow
pointing TOWARD Port on Cylinder. For Meter-In Control, install
valve with Full Flow arrow pointing AWAY FROM Port on
Cylinder. Generally, best results are obtained with Meter-Out
Control.
Metered flow is adjustable. Clockwise turning of Metering
Needle (Item #4) reduces flow — Counterclockwise adjustment
increases flow. After obtaining desired flow by adjusting
Metering Needle, securely tighten Lock Nut (Item #1) to reduce
the possibility of changes from unauthorized personnel or due
to vibration.
Service Procedures:
!
CAUTION: Always shut off air supply and depressurize all
air lines connected to the valve before servicing unit.
1. Using a hex head wrench, loosen both set screws (Item
#11) at the bottom of the valve.
2. Unscrew and remove plug assembly (Item #9).
3. Remove spring (Item #7) and poppet (Item #8).
4. Remove body o-ring (Item #10) from plug assembly and
poppet o-ring (Item #6) from poppet and discard both
o-rings.
5. Unscrew and remove lock nut (Item #1).
6. Remove retaining ring (Item #2) and discard.
7. Unscrew and remove metering needle (Item #4) and
discard needle o-ring (Item #3).
8. Inspect the needle seat, poppet and poppet seat for nicks,
voids, pits and deep scratches. Replace the entire valve if
any of these irregularities are present.
9. Using a non-detergent hydrocarbon base oil or grease,
lightly lubricate all o-rings found in the service kit and
place them on their respective components.
10. Screw in the metering needle and install the new retaining
ring.
