Product Overview
4
The ROM and ROMpak 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, a local indicator and manual override options together with a wide range of voltages.
Features:
Motor
• Standard duty cycle induction motor - S3. F insulation class for all ROM and ROMpak actuators
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 override will not rotate except on ROMH-1 to ROMH-3, ROM-1 & ROM-A
Gear Train
• High alloy steel gear trains provide self-locking function to avoid valve back drive
• Gear trains are factory lubricated with a wide temperature rated lubricant
Mechanical Stops
• Externally adjustable mechanical stops are provided on ROM-2, 3, 4, 5 & 6 actuators
Working Conditions
• Ambient temperature: -30 to +70 ºC†
• Humidity: 30% to 95%
Various Options
• Anti-condensation heater
• Additional limit switches
• Conduit entries M20 x 1.5p
• Torque switches*
* Excluding ROM-H1, ROM-H2, ROM-H3, ROM-1 & ROM-A.
† Excluding 12/24 VDC.
Certificates
• ISO 9001, CE, CSA, BV
The ROMpak
The ROM range of actuators is now enhanced with the addition of the ROMpak actuator. The ROMpak has a self contained control package with local controls, status indication relays, isolated control circuits and support for Rotork control options such as Folomatic, Pakscan and other bus systems.
• Small, compact & lightweight
• Manual override
• Externally adjustable mechanical stops*
• Local control unit (local/remote, on/off)
• Status relays
• Phase rotation correction
• IP68 (10m-100hr)
• 12/24 VDC, 110/220 VAC single-phase and 220/380/440 VAC three-phase*, 50 Hz and 60 Hz
• Position indication via local mechanical indicator and LED’s
• -30 to +70 ºC† operation
* Excluding ROMpak-1 & ROMpak-A.
† Excluding 12/24 VDC.
Various Options:
• Bus communications including: Pakscan, Profibus®, Modbus and Foundation Fieldbus®.
• CPT & Folomatic
