New products CT6 and BT6 explosion-proof actuators

Explosion-proof instructions Electric actuators, as electrical devices, are a potential source of detonation. Explosion-proof actuators, by design, avoid high temperatures and sparks during operation. Should an explosion occur inside the actuator, the housing is capable of preventing internal sparks and explosions from coming into contact with the outside. And the housing is strong enough not […]
