Installation site information:
The valve installation site should be easily accessible and provide sufficient room for service and removal of
actuators. Manual shut-off valves should be located up and downstream of the control valve, to facilitate
service and repairs without draining the piping system. The control valve should preferably be installed
vertically with the actuator installed in the upright position. When carrying out inclined to horizontal
installation of actuators the stanchions must be aligned vertically one above the other.
Pipelines should be insulated to protect actuators against high temperatures; here sufficient room is to be left
for servicing the stem seal pack. For trouble free function of the control valve the pipe immediately upstream
of the valve should be straight for the length of at least 2 x DN and the pipe immediately downstream for the
length of at least 6 x DN.
Actuator mounting-and removal information:
The control valve is normally supplied complete with actuator. It is not permitted to remove or replace an
actuator on systems in operation, under operating temperature and pressure. For conversion or service, the
actuator mounting procedure should follow the actuator SDI. During mounting procedure the plug should
NOT be rotated with downward pressure. Ensure adherence to max. valve operating forces for actuator
replacement.
Actuator removal:
In addition to general mounting guidelines and TRB 700 the following points should be observed:
♦ Pressure free pipe system
♦ Cooled fluid
♦ Drained pipe system
♦ With corrosive or aggressive fluids the pipe system should be vented.
♦ Work to be performed by qualified personnel only.
Danger
Caution:
Electrical wiring must be in conformance with directives for high-voltage installations; Line
voltage and frequency must be identical with data on the product nameplate.
Voltage supply line wiring:
Wire gauge min. 1mm
Electrical isolation:
Prior to the removal of the actuator cover, e.g. for mechanical maintenance and adjustment,
line voltage supply must be disconnected by means of an isolation switch, safeguarded
against inadvertent operation.
Danger
Electrical connection:
• Lead cable through the PG screw fitting to the respective terminals, and then remove
insulation from wire tips. Inside the actuator, wires must be routed or fastened so that
they are protected against damage by moving or rotating parts and removal or
replacement of the actuator cover.
• Fasten ground wire to ground terminal. (Not applicable for 24V version )
• Tighten cable adapter to achieve a reliable tension relief
Mounting accessories: ER2 (ER135)
Mounting and testing shall follow accessory by-pack installation instructions
