Features & Benefits
Fully configurable fail-safe
Setting of position (extended, retracted) or intermediate position, flow or power. Possibility to set delay for entering/leaving failsafe mode for a reliable and optimal fail-safe function. Ability to perform quick health check of fail-safe function.
Best-in-class control
Accurate and fast control response even at very low flows in common part load conditions. Ensures full modulating control for the complete operating stroke leading to world class control and efficiencies.
