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. Service or modification should
be carried out in accordance with the actuator SDI. During mounting procedure the plug should NOT be
rotated with downward pressure. Ensure adherence to max. valve operating forces when replacing actuator.
These are:
Commissioning:
•
Prior to commissioning check information on material, pressure, temperature and flow direction in
conjunction with the installation piping system plan.
•
Follow TRB 700.
•
Impurities in the piping system and valves, such as dirt, welding beads etc. will cause the system to leak.
•
Prior to commissioning a new installation or re-commissioning after repairs or service, ensure that:
Correct installation- and assembly work has been completed.
Only qualified personnel carry out commissioning.
Correct functional position of the valve is ascertained.
Maintenance of existing protective facilities is carried out.
