When power is applied to the actuator, the motor drives
the gear assembly, and pushes down on the valve stem
against the force of the valve return spring.
When power i s removed from the actuat or , the
actuator ret r ac ts and allows the valve return spring to
move the valve stem up, in the di r ec tion of its norm al
position. ( S ee Figure 2.)

Observe the fol lowing recom mendations when
mounti ng the actuator:
• Make sure the actuator is easily accessibl e for the
electrical connect ions.
• Make sure the actuator is free of thermal
insulati on materi al.
• Leave at least 0.8 in. ( 20 mm) c learance above
the actuator for m ounting purposes. (See Figure
3.)
To mount the actuator on a VG5000 v alv e:
1. Place the thr eaded c oupling over the valve stem
and the bonnet.

2. Rotate the actuator to the desired posit ion and
tighten t he c oupling securely by hand.
Note: Never use the ac tuator as a mounting lever.
!
CAUTION: Equipment Damage Hazard.
Mount only on a valve t hat is
piped within 90° of the vertical
position, so i t is free of dri pping
water, which could ent er the
housing and damage the
mechanism and motor. (See
Figure 4.)
