Actuator Technology

Something not many people know: EBRO produces its own actuators - and has been doing so for
30 years. For EBRO customers this means that butterfl y and gate valves can always be equipped
with the most suitable actuator. No compromises, just the best possible match of components - this
is what the EBRO actuator series stands for. Pneumatic actuators, single or double acting, have
been proven for decades. However, industrial process air is expensive. Energy effi ciency is there-
fore the topic of the day. As a manufacturer of valves and actuators, EBRO can specifi cally match
single product components according to customer requirements and within the scope of operating
conditions, thus substantially reducing regular operating costs.
