Introduction
Follow these instructions when installing, operating, or servicing
the product.
Installation
This kit contains screws, gaskets and a completely assembled
Flow Control Section, ready for installation on any Series CC
valve.
1. Depressurize all air lines connected to the valve before
dissassembly.
2. Remove Body from Base making sure that none of the gasket
material sticks to the base.
3. Assemble with; Gasket No. P69922 (Fig. 1) between Flow
Control Assembly and Body; and Gasket No. P12207 (Fig. 2)
between Base and Flow Control.
Note: Locating pin ensures proper orientation.
4. Secure the assembled components using the longer socket
cap screws provided. Torque to 11.3 to 14.1 Nm (100 to 125
in. lb).
Note: If Flow Control Assembly is removed, Gasket No. P12207
should be used between Base and Body.
Operation
The Integral Flow Control Section eliminates the need for two
separate flow control valves. Air is exhausted through a single
valve port, requiring only one muffler or piped exhaust connection.
Adjusting screws with fine threads have metering tapers designed
to give a wide range of control without extreme sensitivity.
Adjustment is made with an ordinary screwdriver; friction-lock
prevents changes in setting due to vibration.

WARNING
To avoid unpredictable system behavior that can cause personal
injury and property damage:
• Disconnect electrical supply (when necessary) before
installation, servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected
to this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure,
temperature, and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must
be performed by knowledgeable personnel who understand
how pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical
supplies (when necessary) should be connected and the
product tested for proper function and leakage. If audible
leakage is present, or the product does not operate properly,
do not put into use.
• Warnings and specifications on the product should not be
covered by paint, etc. If masking is not possible, contact your
local representative for replacement labels.
IMPORTANT. Before making adjustment, release lock screws on
retaining plate. Turn metering screws counterclockwise for more
air flow and faster piston movement.
The Flow Control Section has been designed to give “Meter-Out”
control of exhaust air flowing FROM Cylinder TO Valve Exhaust
Port. For best results, air supply to valve must be connected to
port “A”. Lines from cylinder ports on valve to ports on cylinder
should be kept as short as possible to reduce “jump” of the
cylinder piston when valve shifts. However, it is possible to connect
air supply to port “B” which results in “Meter-In” control of air
supply to cylinder.
