Installation
See table 2 for actuator parts/key numbers referenced in this Installation section. See table 3 and also refer to the
appropriate Baumann valve instruction manual for valve parts referenced in this Installation section.
1. Before starting, ensure you have the correct actuator part number for the necessary stroke and locate the following
parts: stem locknuts, travel indicator, bonnet, yoke drive nut, plug and stem assembly, packing follower. Refer to
the assembly instructions for the appropriate Baumann control valve for parts identification.
2. Place the body of the valve in a vise. Clamp the flat end faces of the valve.
3. Connect the actuator wires in the proper setup. The black and red wires should be connected to power and the
black and white wires should be connected to the input signal. Cycle the actuator to the upper travel point.
4. When mounting the actuator assembly to the valve body, the hole in the yoke plate should fit over the top of the
valve stem. Tilt the top of the actuator back at an angle so you can access the top of the valve stem.
5. Position the yoke drive nut over the valve stem with the flat side facing up [the rounded side should face down,
toward the top surface of the yoke plate].
6. Thread two locknuts onto the valve stem. Finger-tighten both nuts down as far as possible. Lock the nuts together
using two wrenches to counter-tighten them. By turning the locked nuts with a wrench, you will be able to turn the
valve stem in step 8 without damaging the surface of the valve stem.
CAUTION
When assembling or disassembling the valve, do not turn the valve stem while the plug is touching the valve seat. This will
damage the valve's seating surfaces.
7. Tighten the yoke drive nut by hand.
8. Apply anti-seize compound to the first few threads of the valve stem. Lift the valve stem up so that the plug is off
the seat. Turn the valve stem so that the threads begin to catch in the lower end of the stem adapter (key 26). Using
one wrench placed on the lower counter-tightened nut and one wrench on the stem adapter (key 26), turn the
valve stem up until you feel resistance, then back off or unscrew the stem adapter one full turn. Be sure that the
actuator yoke plate is firmly seated on the bonnet.
9. Using a hammer and punch, tighten the drive nut.
10. Place the spacer (key 59) on top of the stem adapter (key 26). Place the travel indicator disk on top of the spacer
and tighten the stem connector (key 25) to the stem adapter (key 26) until rigid.
11. Check the seat leak and adjust the stem adapter down as required to achieve shutoff.
12. Using two wrenches, unlock the two counter-tightened locknuts. Holding the stem adapter (key 26) with a
wrench, turn the locknuts, one at a time, up until they are locked together against the stem adapter (key 26).
13. With the valve in the closed position, add the travel indicator sticker (key 56). The closed line on the travel
indicator sticker (key 56) should be aligned with the travel indicator (key 58) at this point.
