RAS SMART Electric Actuator
10–30 NmIP67
Compact, lightweight SMART actuation for small-bore valves.
The RAS series is RIFT’s compact SMART actuator: up to 30 Nm, rated IP67 and light enough to mount directly on small ball and butterfly valves without additional support.
Every RAS carries RIFT’s SMART™ technology, so it can be configured, operated and diagnosed from an Android phone, tablet or PC over Bluetooth. Optional features — modulation, failsafe, wiggle and speed control — can be enabled before installation or on site.
A manual override handle is fitted as standard and drive adaptors are available in 9 mm, 11 mm and 14 mm, so the RAS suits most commercially available quarter-turn valves.
- IP67 protection as standard
- Bluetooth set-up from Android devices
- On/off or 4–20 mA modulating control
- Failsafe, wiggle and speed control options
- Manual override handle fitted
- Low-power RIFT motor technology
