5.5 Valves with actuator
WARNING
Impermissible loads resulting from operating conditions, add-on parts and valve-
mounted components, e.g. actuators
Leakage from or rupture of the valve body!
▷
Lay the piping in such a way that detrimental thrust forces and bending forces
are kept away from the valve body.
▷
Additional loads, e.g. traffic, wind or earthquakes are not taken into account
for standard variants; these require a separate design.
▷
Support the valve including add-on parts and valve-mounted components.
Electric actuators
DANGER
Unqualified personnel performing work on valves with actuator
Danger of death from electric shock!
▷
Ensure that 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
Flooding of electrical devices such as actuator, control box, solenoid valve, limit
switches, etc.
Danger of death from electric shock!
▷
Operate electrical devices in flood-proof rooms only.
▷
Do not expose electrical connections to any moisture.
▷
Voltage and frequency must match the data stated on the name plate.
WARNING
Incorrect connection to the mains
Damage to the power supply network, short circuit!
▷
Observe the technical specifications of the local energy supply companies.
Mounted actuators are factory-set and ready for operation. Adjust travel stops and
torque limit switches to the operating conditions if required.
5.6 Insulation
WARNING
Cold/hot piping and/or valve
Risk of thermal injury!
▷
Insulate the valve.
▷
Fit warning signs.
For any insulation fitted on the valve observe the following:
▪
The valve's function must not be impaired.
