  • Product Info
  • Literature

Overview

Control central heating and cooling, fan coil systems, radiators and convectors. Depending on the model, it can be controlled by a low voltage SPST or SPDT switch, pulse-width modulated 24 Vac signal, or floating input, modulating controller.

Features

  • Use with two-way or three-way valves.
  • Double insulated actuator.
  • Five foot plenum-rated cable.
  • Quick and easy replacement of moving parts.
  • Actuator head installation does not require draining the system.
  • Selectable/switchable electronic fail safe normally open or normally closed.
  • Available with valve bodies with 1000-series 2-way and 6000-series 3-way cartridges for new construction.
  • All VC Series actuator-valve combinations provide 60 psi close-off.
