Samson 3510 Series - Default Chapter; Versions

EB 8091 EN 3-3
Design and principle of operation
pressure is increased enough to over-
come the force exerted by the springs.
The actuator's direction of action can be re-
versed, if required. Refer to the operating
and mounting instructions of the pneumatic
actuator, e.g. uEB8310-1 for Type3271
and Type3277 with 120cm² actuator area.
3.1 Versions
With insulating section/bellows seal
The modular design allows an insulating sec-
tion or bellows seal to be tted to the stan-
dard valve version.
If valve accessories (e.g. positioner, limit
switch etc.) are to be mounted to the valve
version with anges, we recommend mount-
ing an insulating section or bellows seal. This
provides more space to mount valve accesso-
ries.
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
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.
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).
