Functions and Applications：

The SMC/JA series electric valve actuators are part-turn actuators, suitable for ball valves, butterfly valves and other similar valves, as well as electric dampers.They feature a combined structure, composed of an SMC multi-turn electric actuator and a JA part-turn reduction unit.

The applicable environmental conditions of this series, including ambient temperature, humidity, altitude and protection rating, all meet the levels of corresponding SMC standard products.

The technical performance and electrical control principle are also the same as those of the corresponding SMC products.
