FAQ Question?What does the ‘OE’ function mean on the label? AnswerOE stands for “Oeffnet bei Entlastung” in German, which translates to “opens on pressure relief”. This means it is a “fail-open” or “spring-to-open” actuator. If control air pressure is lost, the internal spring will push the valve to the open position. Question?Can this actuator be used with a valve from a different manufacturer? AnswerWhile technically possible if the mounting yoke, stem connection, and travel stroke are compatible, it is strongly recommended to use this actuator with the originally intended ARCA valve body. Mismatched components can lead to poor control performance, damage, and safety risks. Question?The label lists DN 50, but the actuator seems separate. What does this refer to? AnswerThe DN 50 (Nominal Diameter 50 mm) refers to the size of the control valve body this actuator was originally mounted on. The actuator itself is sized to provide the necessary force and stroke to operate a DN 50 valve under the specified process conditions. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
