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