DANGER
Unqualified personnel performing work on valves with actuator
Danger of death from electric shock!
▷
Ensure that the connection to the power supply and the process control system
is performed by a trained electrician.
▷
Observe regulations IEC 60364 and, for explosion-proof models, EN 60079.
DANGER
Work on valves with energy storage, e.g. spring mechanisms or compressed air
storage
Danger to life resulting from incorrect assembly
▷
Ensure that work on the actuator is performed by qualified specialist personnel.
▷
Mount/remove the actuator in accordance with the operating manual.
NOTE
If the valves are fitted with actuators, ensure that the actuator's operating manual
is also observed.
On valves with electric, pneumatic or hydraulic actuators, the actuator strokes/forces
must be limited.
Electric actuators
Electric actuators are ready for operation and wired as follows:
▪
Valve "CLOSED": travel-dependent
▪
Valve "OPEN": travel-dependent
The wiring diagrams are located in the terminal boxes.
Pneumatic/hydraulic actuators
For pneumatic or hydraulic actuators, the control pressures specified in the order
confirmation must be observed. Non-observance may damage the actuator.
If required, consult the manufacturer for closing and opening torques or actuating
forces.
5.5 Insulation
NOTE
Any insulation fitted on the valve must not impair the valve's function. The sealing
areas at the cover/bonnet joint and at the stem passage (gland packing) must be
directly accessible and visible.
