3-Way Modulating Valve (Chilled Water, Hot
Water or Combination)
Three-way modulating control valves for MicroTech are
designed to regulate the flow of hot or chilled water or
the combination. They consist of a nickel plated brass
body and stem with chrome plated brass ball valve, with
a spring return, proportional actuator. The optional valve
accessory is shipped separate from the unit ventilator
for field installation to prevent shipping damage and to
provide flexibility in making the field piping connection.
