Single Sub-base Mounting

Between the valve and the sub-base is a
locating pin which assures accurate alignment
of valve and sub-base. Valves are secured with
two mounting screws.
The mounting of this valve may be achieved by
one of two methods:
1. Sub-base may be bulkhead mounted using
1/4-20 threaded mounting holes on the
bottom of the sub-base.
2. The same holes are counter-bored from the
top of the sub-base to accept #8 screws for
surface mounting.
Valves and sub-bases may be ordered
separately; however, factory assembly is
available at a nominal charge.
