AP3260/3600, Panel Mount
Revision 3
January 31, 2013
Note: This procedure is intended for panel mount of AP/AZ/AK/3260/3600/4600 Series
3
valves.
Note: Recommended panel hole diameter: 0.78 inch (19.8 mm).
A. Required Tools and Equipment
• 1/2 inch socket and wrench
• 1/2 inch socket and torque wrench, 75 in-lb (8.5 Nm)
• 1 inch wrench (open end or adjustable)
• Strap wrench to hold wheel (optional)
B. Wheel Removal (Refer to
1. Remove the valve from the double plastic bag.
2. Close the valve by turning the wheel (#3) fully clockwise.
3. Using a small flat screwdriver or similar tool, pry the closure (#1) off the top of the wheel.
4. Firmly holding the wheel in place (by hand or with a strap wrench), use a 1/2 inch socket and
Figure 1)
wrench to loosen the lock nut (#2). Remove the lock nut and wheel.
Note: The wheel must not rotate counterclockwise during loosening of the lock nut. If the
wheel rotates, re-tighten the lock nut against the wheel and repeat step B.2.
C. Panel Mount (Refer to Figure 1)
1. Remove the panel mount nut (#5) from the unit.
2. Place the valve through the panel hole, position the valve as desired, connect the valve into
piping system and replace the panel mount nut onto the unit.
3. Using a 1 inch wrench, tighten the panel mount nut firmly against the panel.
D. Wheel Replacement (Refer to Figure 1)
1. Place the wheel back on the stem (#4), and turn the wheel clockwise until it stops.
2. Rotate the wheel counter-clockwise one full turn.
3. Holding the wheel in place, screw the lock nut onto the stem until it stops against the wheel.
4. While holding the wheel from turning (by hand or with a strap wrench), use a 1/2 inch socket
and torque wrench to tighten the lock nut against the wheel with 75 in-lb (8.5 Nm).
5. Reinstall the closure by pressing it into the top of the wheel.
E. Valve Testing
1. Open and close the valve several times to verify the actuator operates correctly. Leave the
valve in closed position.
2. Connect the valve inlet to 60-100 psig (4.1 - 6.9 bar) pressure nitrogen source line. Pressurize
the valve inlet. Verify there is no audible leakage across-the-seat. Open the valve and verify
that there is no flow restriction in the valve. Close the valve.
3. Perform a helium leak test to verify that the valve does not leak across-the-seat. Leak test
procedures depend greatly on equipment and operator preference. Refer to SEMI F1 for
typical leak testing protocols. If it is not possible to perform a helium leak test, then a
pressure decay test could be performed using inert gas.
