Design and principle of operation
3.2 Versions
Materials
The valve body can be manufactured on re-
quest in various materials (e.g. 1.4435).
Connections
The Type 3249 Valve can also be delivered
with the following end connections:
−
Welding ends according to
DIN EN ISO 1127, ISO 2037 (SMS) or
NFA 49249
−
Threaded connections according to
DIN 11851 (11887)
−
Threaded connections according to SMS
or IDF
−
Clamp connections according to
ISO 2852, DIN 32676 or BS 4825
−
Flanges
−
Aseptic flanges according to DIN 11864
with groove or collar
Optionally, the valve is available with a test
connection with nipple fitting
Actuators
In these instructions, the preferable combina-
tion with a SAMSON Type 3271 or
Type 3277 Pneumatic Actuator is described.
The pneumatic actuator can be replaced by
another pneumatic actuator in a different
size, but with the same travel.
Î
Observe the maximum permissible
actuator force.
If the travel range of the actuator is larger
than the travel range of the valve, the spring
assembly in the actuator must be preloaded
so that the travel ranges match. See associ-
ated actuator documentation.
As an alternative, the control valve can be
combined with a Type 3274 Electropneumat
-
ic Actuator.
