I. DESCRIPTION AND SCOPE
The Model 2296 / 2296HF is a pneumatically actu-
ated, sliding stem globe-style control valve. Available
in Cast Bronze or 316L SST body material, in sizes
1/2" - 2" (DN15 - DN50). Model 2296HF is available
in Cast Bronze body material and only in sizes 1-1/2"
and 2" (DN40-DN50). Internal de sign is a “push down
to close” arrangement.
Failure position is determined by actuator for:
"D" = Direct action; on increasing air loading pressure,
the actuator stem extends. Fail-safe position is with
the stem retracted.
"R" = Reverse action; on increasing air loading pres-
sure, the actuator stem retracts. Fail-safe position is
with the stem extended.
This valve is designed to control general service through
moderately cor ro sive applications, but may be applied
in cryogenic applications also.
