Samson 5824 - Type 5825: Force-Locking Attachment; Type 5825: Form-Fit Attachment; Installing the Control Valve into the Pipeline

EB 5824-2 EN 5-3
Installation
3. Position the clamps of the stem connector
(16) included in the accessories on the
ends of the actuator stem and plug stem
and screw tight.
5.4.3 Type5825:force-
locking attachment
Fail-safe action "actuator stem extends"
The actuator stem must be retracted before
the actuator can be mounted onto the valve.
The stem can be retracted either mechanical-
ly or electrically. Both methods are described
below.
Retracting the actuator stem mechanically
1. Unscrewfrontcoverandplacea4mm
Allen key on the red actuating shaft.
2. Retracttheactuatorstem:turnAllenkey
counterclockwise and only as far as the
top end position which is at the point
where the torque-dependent limit switch
isactivated(seeFig.5-4).
Risk of damage to the actuator by turning it
too far.
Î Move the actuator stem only as far as the
top end position.
3. HoldAllenkeyinplaceandfastenvalve
and actuator together using the coupling
nut.
Tightening torque 20Nm
Remove Allen key and carefully refasten
the front cover.
Retracting the actuator stem electrically
1. Unscrew front cover.
2. Perform electrical wiring according to
section5.6andcarefullyrefastenthe
front cover.
3. Retractactuatorstem:
− Switch on the supply voltage and retract
the actuator stem electrically until it
reaches the end position by applying a
signal to the input (see the 'Operation'
section).
4. Fasten valve and actuator together using
the coupling nut.
Tightening torque 20Nm
Fail-safe action "actuator stem retracts"
Î Place the actuator on the valve connec-
tion and fasten with the coupling nut.
Tightening torque 20Nm
5.4.4 Type5825:form-tat-
tachment
Î For fail-safe action “actuator stem re-
tracts” and “actuator stem extends”,
mount actuator as described in sec-
tion5.4.2.
5.5 Installing the control valve
into the pipeline
Î Install the valve into the pipeline accord-
ingthespecicationsinthemounting
and operating instructions of the valve.
