AUMA solution for multiport valves
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.
