MZ18A
The MZ18A actuator is specifically designed to provide modulating control together with the VZ22, VZ32 and VZ42 series of small linear valves. The MZ18A is used in fan coil units, induction units, small reheaters and recoolers, and for zone control applications. The actuator is compatible with controllers providing 0-10 V or 2-10 V output signals. Reliable long term operation is ensured by the fact that no mechanical feedback
potentiometer and no mechanical end switches are needed.
Due to an automatic synchronization function the close-off point is self-adjusting. Based on a running time of 150 seconds, valve positioning and flow adjustment is very exact.
