Valve Automation Centre
The Valve Automation Centre has a state of the art workshop in which well trained technicians mount pneumatic, hydraulic and electric actuators on valves. Valves and actuators can be modified according to customer specifications and be equipped with options such as valve positioners, limit switches, pilot valves and more. Five pressure test benches allow testing of valves upto DN1200/48”. The applicable standards are API598 and EN12266 and any other customer specified protocols can additionally be performed.

In industrial and maritime environments electric actuators must be suitable to operate in the most challenging conditions. Therefore the Econ® Fig. 7907 ELA actuator has a robust design and can be mounted on all ball valves, butterfly valves, damper valves and plug valves with an ISO 5211 mounting flange. In most cases the Econ® valves can be assembled with these ELA actuators directly. The use of a bracket and coupling is not needed. The ELA actuators offer reliability, ease of use and an excellent price-quality ratio.
