Actuators

MIN/MAX ACTUATORS

FOR CONSTANT VOLUME FLOWS WITH VMIN/VMAX SWITCHING IN AIR CONDITIONING SYSTEMS

Actuators for mechanical self-powered CAV controllers Type EN, RN, or VFC, and for flow adjustment dampers Type VFR

  • Switching between two volume flow setpoint values, e.g. for daytime and night-time operation
  • Supply voltage 24 V AC/DC or 230 V AC
  • Control input signal: 1-wire control or 2-wire control (3-point)
  • Potentiometer or mechanical stops
  • Positive lock connection with CAV controller
  • Retrofit possible
