| AXT 211: Thermal valve drive
How energy efficiency is improved
Safe operation within the scope of efficient closed-loop control
Areas of application
Operating through and 3-way unit valves of the VUL, BUL, VXL and BXLseries or other popular makes of unit valves. For controllers with aswitching output, 2-point control quasi-continuous control with'pulse-pause' signal, in combination with intelligent unitary controlsystems.
