ments of the New York City's Board of Air
Resources. The valve body dimensions are the
same as those shown at the right for the RV-2000
and RV-2100 Series valves. Dif ferences are: 1)
The top and bottom valve end caps are taper
pinned to the body to prevent removal. 2)
The
pressure adjustment seal screw and washer, once
installed by the customer , cannot be removed to
prevent tampering with the set pressure.
