High-precision actuation for multiport valves

Added - 13.11.2019

AUMA offers a new high precision automation solution for multiport valves based on SAVEx electric actuators with adjustable motor speed. The actuators support up to 16 ports with a combination of short operating times and excellent precision, thanks to their variable speed motors. Positioning accuracy is better than 0.3°, making the actuators suitable for the most challenging applications in this market. Switch valves with lift plug design are also supported.

Multiport valves find application in the oil and gas industry in sampling systems for multiple wellheads. Fluids from each well in turn can be directed to a single sampling system, allowing operators to monitor current production in detail. The positioning accuracy required makes this a challenging application for actuators.

AUMA’s SAVEx variable-speed actuators are ideal for this task. For rapid switching, the actuator motor runs at high speed over most of its travel. Just before the valve plug reaches the target port position, however, the speed is considerably reduced. By virtually eliminating overrun, this allows extremely precise positioning.

Switch valves with lift plug design require an even more demanding actuation solution since two different movements have to be coordinated: before the plug can rotate to the desired outlet it has to be lifted from its seat. This requires a second actuator. AUMA’s clever and simple solution is to use two actuators in a master-slave configuration that appears to the DCS as a single actuator. The intelligent actuator controls handle the complete sequence of movements and the safety interlock.

AUMA has also expanded its list of communication protocols supporting multiport and switch valve functionality: Foundation Fieldbus is now also available, in addition to Profibus DP, Modbus RTU and Modbus TCP/IP

New MWG - Sales team training

Added - 28.10.2019

The actuator control unit, or MWG, is the component in the actuator that encodes the commands set into the microprocessor of the AC controller and allows non-intrusive set-up. In its latest version, the position indicator within the MWG, based on a reference operation during commissioning, automatically adjusts to the valve end position. 

The AUMA UK sales and management team were at head office in Clevedon for a thorough training session on the new component, which is fully compatible with previous models. Go on, ask them anything!

State of the Electric Actuation art; Feature article in PII

Added - 24.10.2019

Our very good friends over at Process Industry Informer magazine have published an article by our MD Paul Hopkins, looking at the current state-of-the-art in electric actuation, touching on topics like modularity, edge computing and the IIoT, the rise of the service-led approach, the benefits of variable speed valve actuation and so on. Paul also discusses the ACE Technician programme and the value of valve actuators in systems integration and long-distance process communications. Including a few case studies for good measure.
