Best for applications related to water supply and sewerage systems
Limitorque valve control
JMB series
The Limitorque JMB series valve actuators, based on the SMB series valve actuators with a lot of achievements, are equipped with an interlock switch that interrupts the electric circuit during manual operation.
In addition to the robust and highly accurate structures and enhanced control mechanism, the design with superior maintainability guarantees stable operation for a long time.
To meet the demands in a wide range of fields, we offer eight unit sizes and a wide variety of reduction ratios.

Application
– Water supply and sewerage systems, as well as thermal and hydropower plants, petroleum oil, chemical, ship, vessel, and papermaking.
– JMB actuators can be attached directly to multi-turn-type valves (such as hydraulic gates, gate valves, glove valves, and through gates).
– They can be attached to part-turn-type valves (such as butterfly valves, plug valves, and dampers) in combination with an actuator for part turn-type valves.
