M9000-560 Ball Valve Linkage Kit and M9000-561 Thermal Barrier Installation Instructions6
Mounting
Mount the VG1000 Series Ball Valves with the actuator
at or above the centerline of the horizontal piping, as
shown in Figure 7. This mounting position prevents
water or condensation from flowing into the actuator. To
minimize heat transfer, wrap the valve and piping in
insulation.
Mounting M9000-560 Linkage to M9203
Actuator
To mount the actuator to a ball valve, rotate the valve
stem manually several times using an adjustable
wrench to break the torque that may have built up
during long-term storage.
Mounting the M9203 Actuator to Spring Return Port
A (Coil) Open
To mount the actuator to Spring Return Port A (Coil)
Open:
1. Turn the valve stem to the position outlined in
Figure 8.
2. Mount optional M9000-561 Thermal Barrier to the
valve if fluid temperature exceeds 212°F (100°C).
See the Mounting the Thermal Barrier
section for
more information.
3. Insert the drive shaft into Side B (Figure 9). The
drive shaft is keyed for one-way assembly. With
gentle pressure applied, rotate the drive shaft until
the key aligns and the drive shaft falls into place.
4. Install linkage base on Side B using the two
#8-32 x 0.625 in. long screws (Figure 10). The
recommended torque is 29 to 33 lb·in.
(3.3 to 3.7 N·m).
IMPORTANT: In steam applications, install the
valve with the stem horizontal to the piping. Failure
to follow this precaution may shorten the life of the
actuator.
