Valve actuator
Introduction of electric components
Dedicated motors (Characteristics of motors for electric valve: Maximum startup torque/Low inertia)
| Standard motor | Size: #2 – #350 (0.2 – 35 kW) | Class E/B as standard | Option: Brake and insulation class (Class F/H) |
|---|---|---|---|
| Motor for nuclear power (in a containment vessel) | Size: Same as standard motor | Class H, radiation-proof type | |
| DC motor | Size: #2 – #200 (0.2 – 15 kW) | Class B as standard | Option: Brake and insulation class (Class F/H) |
| AC motor for hydraulic gate (Genera-purpose characteristics) | Size: 0.2 – 37 kW | Class E/B as standard | Option: Brake, cooling fan, and insulation class (Class F/H) |
| Single-phase AC motor | 0.2, 0.4, 0.5kW | Class F, with built-in capacitor C 100 V / 200 V) | |
| Air motor | 2R to 10R (11 to 103 Nm @ 0.5 MPa) | Working air pressure .3 to 0.6 MPa | |
| Tandem-type motor | A motor made by combining standard motor and air motor (for emergency) | ||

[New product] Compact single-phase motor
This is a single-phase outdoor motor equipped with a built-in capacitor to enhance user-friendliness. Subject actuators are compact models – JMB-04M1, JMB-03M1, and SMB-000.
