V51E (FIGS. 7, 8, 9)
The V51E valve is intended to provide normally open,
direct operation (valve open when pneumatic pressure off),
the actuating arm points to the right as in Fig. 7. For a
normally closed system, the arm projects to the left as in
Fig. 8. If it is necessary to field-convert the valve, remove
only the cotter pin, washer and arm. Reverse the arm and
reinstall.
