Valve actuators for control valve bodies or on-off function. Explosionproofed in acc. with
"flameproof enclosure" and dust ignition proof, PTB tested. Installation in hazardous areas zone 1, 2,
21, 22. The actuators are 100% overload protected and can be stopped in any position. The controller
must be stable and should not pulse. Application: For industrial plant. For
Offshore
applications we
recommend the special types
EXV-8.../CT and EXV-8.../VA.

/L16
Special Type with running time ~16 sec/mm.
The cable of the actuator must be installed in a fixed position
and protected against mechanical damage.
For installation, use and maintenance the official standards
and rules must be applied.
3) With horizontal installation position of the actuator, the
two spacer rods must form a vertical level.
Temperature class T6 is only for the actuator, you have to
guarantee max. temperature of valves and tubes on site.
The EEx actuators may only be opened by the
manufacturer to guarantee explosionproof and for
warranty.
For outdoor installation a heater and a weather protective
housing against rain, snow and sun is required.
After installation all componetes must fulfil the protection class
IP65 acc. EN60529.
