Item Number 129-123-04, Rev. BA Page 1 of 4

Product Description

The No. 6 Damper Pneumatic Actuator is a heavy

duty, rolling diaphragm, spring return actuator

designed to drive large dampers, centrifugal

refrigeration inlet vanes, and other applications

requiring a large, effective diaphragm area and long

stroke.

Required Tools

• Flat-blade screwdriver

• Adjustable crescent wrench

• Pliers

Prerequisites

• Ensure all kits are ordered and available for

installation. Kits are listed with each

mounting application.

• Have the damper manufacturer drill

mounting holes.

• Have the damper manufacturer weld

mounting lug to damper frame for Frame

Mounting—Type B installations.

These assemblies are designed for 90° damper rotation. NOTE: Clevis mounts in crank radius hole No. 1 for 90° damper rotation. 1. Slip 3/4-inch (19-mm) diameter hole in the mounting plate over the damper shaft (Figure 1). Figure 3.

Weld the mounting lug parallel and 5/16-inch (8-millimeter) from the inside edge of the damper frame and perpendicular to it (Figure 6). Weld the lug along both sides. The lug should be as close as possible to the corner of the damper frame to minimize deflection. The damper manufacturer should weld the lug. 3.

Fasten clevis to rocker. Discard crank and other unused parts. 7. The actuator mounting plate has a tendency to pivot at the point where the lug is welded to the damper frame when the actuator strokes. It is recommended that some means be devised in the field to prevent this from happening.
