Zone Valves and Actuators
Zone Valve Actuator – Long Stroke
MZ20A, MZ20B
The MZ20 is an electro-mechanical zone valve actuator designed for
use with the VZ*19* valves.
Reliable long term operation is provided by the optimal design without
feedback potentiometer or end switches.
The actuator provides exact valve position and flow adjustment due to
the 100 second running time.
Contact Schneider Electric for LON actuators for long stroke zone valves.
Note:
5 pc multi packs of the VZ*19C valves are available, consult data sheet for full details and part numbers.
