2 Rotork Actuation Established Leaders in Actuation Technology As one of the world s leading manufacturers of actuation products, Rotork has built up an enviable reputation as the supplier of equipment which is both well developed and durable. With over forty years of experience of long term installation in all environments we have evolved a design of uncompromising reliability. With the addition of the ROM/RBM range, Rotork is complementing its offering of quarter turn actuators with simple specification for small valves. Contents Features of the ROM and RBM Range Product range 4 Optional extras 6 Actuator data 7 Rotork ROM and RBM Range Actuators Small Compact Lightweight Efficient yet simple gearing On-off Modulating option Single phase, phase and DC versions Rotork Controls Ltd, Bath, UK 2 Rotork Controls Inc, Rochester, USA

3 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.

WHERE DISTANCES ARE GREAT BETWEEN ACTUATOR AND CONTROL GEAR, CABLE CAPACITANCE MAY CAUSE CONTACTORS TO STICK ON A.C. CIRCUITS OPTIONAL EXTRAS Torque Switches Cam activated torque switches to provide torque overload protection (available on ROM-2, & 4). Potentiometer Unit Synchronous with output transmission shaft to provide a feedback signal for Position Indicator etc. Modulating Controller Input signal: 4-20mA, 1-5V, 2-10V. Output signal: 4-20mA, 2-10V, 0-100%. External controller: An external unit attached to the actuator is available for ROM-1 and ROM-A actuators. Internal controller: An internal circuit board inside the actuator is available for ROM-2, & 4 actuators. Current Position Transmitter Works in conjunction with the Potentiometer Unit and provides 4-20mA output signal for poistion indication etc. Local Control Unit Local / Remote selection switches Open / Close selection switches (available on ROM-2, & 4 only). Anti-condensation Heater This heater is available for all sizes. Position Indicator Position Indicator can be either 0-100% or 4-20mA. 5
