INSTALLATION
1. Use new, properly reamed, pipe, free from chips.
2. Do not thread pipe too far (Fig. 4). Valve distortion or
malfunction may result from excess pipe in the valve.
Fig. 4—Preparing the pipes.
8. Use two threaded companion flanges, two gaskets
(included with valve), and 16 bolts (with washers and nuts)
for mounting a 4 in.-V5055 Valve. Mount a threaded flange
and gasket on each end of the valve as shown in Fig. 6. Then
screw the pipes into the threaded flanges. Apply dope spar-
ingly, and use wrenches and vises properly as shown in Fig.
4 and 5.
9. Make sure the power supply is disconnected from the
valve actuator. Then mount the actuator on the valve body
and complete the electrical and linkage connections follow-
ing the instructions packed with the actuator.

3. Remove the protective caps from the ends of the valve.
Do not attach the valve actuator until the valve body instal-
lation is complete.
4. Apply good quality pipe dope resistant to action of LP
gas, putting a moderate amount on the male threads only.
Use dope sparingly; if pipe dope lodges on the valve seat, it
will prevent proper closure.
5. Install valve with the gas flow in the direction indi-
cated by the arrow on the casting.
6. Apply a parallel jaw wrench only to the flat next to the
pipe being inserted (Fig. 5). A wrench applied to the valve
body itself, or to the end farthest from the pipe being inserted,
may distort the casting, causing a malfunction. Do not use the
valve for a lever.
7. Be sure the gas flow is in the same direction as the
arrow on the bottom of the valve body.
