Actuators
In these instructions, the preferable combina-
tion with a SAMSON Type 3271 or
Type 3277 Pneumatic Actuator is described.
The pneumatic actuator (with or without

Design and principle of operation
handwheel) can be replaced by another
pneumatic actuator in a different size, but
with the same travel.
Î Observe the maximum permissible actu-
ator force.
Note
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.
The basic pneumatic actuator can be re-

placed by a pneumatic actuator with addi-
tional handwheel or by an electric actuator
(see Information Sheet u T 8300).
