Warning/Caution
Notations
WARNING:
Personal injury or loss of life may occur if you do not
follow the procedures as specified.
CAUTION:
Equipment damage or loss of data may occur if you
do not follow the procedures as specified.
Application
The MX4G61B Series valves are through-port or mixing valves with magnetic
actuators. The actuator is equipped with an electronics module for positioning control
and position feedback. If the power is off, the valve control path A → AB is closed.
The short positioning time, high resolution and high rangeability make these valves
ideal for modulating control of domestic, hot and cold water systems.
