The ROM and RBM Range The ROM and RMB actuators provide quiet and reliable operation for all kinds of small ball valves and butterfly valves, as well as dampers and ventilation louvres. They provide self-locking as standard, local visual indicators and manual override options together with a wide range of voltages. Features: Enclosure IP 67 (NEMA 4, NEMA 4X) waterproof and dust-proof enclosures. Material: Aluminium alloy. Finish: Dry powder coated. Motor Standard extended duty cycle induction motor. H insulation class for ROM-1 and ROM-A; F class for RBM-2 and ROM-2 to ROM-4. Built-in thermal motor protection (15ºC). Position Indicator All models have continuous position indication on the actuator top cover. Manual Override Non-clutch design, the manual operation can be operated without any lever, clutch or brake upon power outage. When the electric motor is operating, the manual overide will not rotate. Gear Train High alloy steel gear trains provide self-locking function to avoid valve back drive. Gear trains are factory lubricated with a high temperature rated lubricant. Mechanical Stops Externally adjustable mechanical stops are provided on ROM-2, & 4 Actuators. Working Conditions Ambient temperature: -5ºC to +60ºC. Humidity: 0% to 95%. Various Options Anti-condensation heater. Additional limit switches. Potentiometer unit (1K Ohm). Local control unit (local/remote, on/off). Conduit entries 1 /2 NPT or M20. Adjustable torque switches. Current position transmitter (output 4-20mA). Modulating controller. Certificates ISO 9001, CE, CSA.
