OPTION SPECIFICATIONS


Option -3:

MANUAL HANDWHEEL. Overrides
the ac tu a tor spring force to
allow man u al strok ing of the valve.
Single acting de sign, side-mounted,
handwheel. For ATO-FC action,
handwheel operator “opens” the valve
against spring force; may be utilized
as a travel stop to prevent full closure.
For ATC-FO action, handwheel
op era tor “closes” the valve against
spring force; may be utilized as a
travel stop to pre vent full opening.
Option -5N_:

CRYOGENIC CONSTRUCTION.
