2-Way Modulating Valve (Chilled Water,
Hot Water or Combination)
Two-way modulating control valves for MicroTech are
designed to regulate the flow 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 field installation to prevent
shipping damage and to provide flexibility in making the field
piping connection.
