Description of actuators GZ-OFV 24V:
Explosion-protected quarter-turn actuators GZ OFV 24 V with explosion protection marking 1ExdllBT4 (type of connection to the valve - according to ISO 5211) are used for controlling pipeline shut-off valves in chemical, oil, gas and power industries.
Explosion-proof actuators can be installed in hazardous areas of class IIB indoors, outdoors under a canopy in accordance with the equipment with explosion protection marking 1ExdllBT4.
The actuators are designed for remote and local control of shut-off valves. Installation position of actuators is any, except for the position with terminal box downwards.
The actuators are designed for operation in repeated-short-time mode S2 with the duration of switching on 15 min. with the frequency of switching on - up to 60 times per hour, for operation in the mode of automatic regulation - up to 600 switching on per hour (in S4 mode).
Operating conditions of GZ-OFV actuators:
environment - air;
possible installation locations - fixed installations indoors and outdoors;
operating temperature range: - 30 ºC to + 40 ºC;
relative humidity (upper value) - 100% at 25 ºC;
enclosure protection - IP67
