Description of electric actuators GZ-OFV(K) 380V:


Explosion-protected quarter-turn actuators GZ-OFV(K) 380V 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 explosion hazardous areas of IIB class indoors, outdoors under a canopy for 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(K) 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
