DA 140 Ex

for operation in hazardous location

DA140 explosion-proof roller-screw actuators provide high force and are capable for operation in a variety of applications on turbines located in hazardous environment. It is applicable for gas turbines and steam turbines that operate in oil & gas, petrochemical and other industries where turbines are located in hazardous area.
Turbine actuators in hazardous area work under heat and vibration impacts. DA140 actuator was designed to ensure reliable operation in such a harsh environment. Diakont have supplied actuators capable to operate under vibration load up to 10 g (from 10 to 500 Hz) and higher.
