2. Insert a new valve body gasket (key 49) and install the bonnet assembly (key 8) with the plug and stem assembly in
the valve. The O-ring (key 12) must be reinstalled by gently stretching over the bonnet and snapping into the gap
between the top of the valve body (key 1) and the bonnet (key 8). This O-ring acts as a dust/moisture seat.
3. Place the actuator yoke over the stem (key 5). While tilting the actuator back, drop the yoke drive nut (key 9) over
the stem (key 5). Run the locknuts (key 27), and travel indicator (key 58) down as far as possible and counter
tighten the locknuts (key 27) to lock.
See the Baumann Pneumatic Actuator Instruction Manual (
) for reassembly and bench range
adjustment.
CAUTION
When assembling or disassembling the valve, do not turn the valve stem while the plug is in contact with the valve seat.
This can damage the seating surface very quickly.
