Design and principle of operation
Î
The fail-safe action must not be used to
control the valve position.
The Type 5825 Actuator does not have a
handwheel (2) on the housing cover. Manual
override is possible, after removing the front
cover, using a 4 mm Allen key. The actuator
returns to its original position as soon as the
Allen key is released.
Version with faster motor
The Types 5824-13/-23/-33 and
Types 5825-13/-23 have a more powerful
motor in a housing at the back of the actua-
tor.

The Types 5825 Electric Actuator with fail-
safe action "actuator stem extends" is tested
by the German technical surveillance associ-
ation (TÜV) according to DIN EN 14597 in
combination with various SAMSON valves.

between approx. 0 and 1000 Ω (use-
able range 0 to 800 Ω ) proportional to
the valve travel. The resistance transmit-
ter is not suitable for retrofitting.
