CHECKOUT AND TESTING
With a 0 to 30 lb/in
line, vary branch line pressure. The difference between
the pressure at which the stem begins to move and the
pressure at full close off indicates the operating range.
The valve begins to close at 3 or 6 lb/in
and is fully closed at 8 or 11 lb/in
depending on the application.
Printed in U.S.A. on recycled
paper containing at least 10%
