Overview

Control central heating/cooling systems, fan coil systems, radiators and convectors. Depending on model, can be controlled by either a low or line voltage SPST/SPDT or floating controller such as a room thermostat, Aquastat control, or flow switch.

Features

  • Two-way or three-way valves.
  • Minimal actuator power consumption.
  • Double insulated actuator.
  • Quick-connect or one-meter cable electrical connections available.
  • Quick and easy replacement of moving parts.
  • Actuator head installation does not require draining the system.
  • On/Off models with six second nominal timing (floating/modulating models available with 120 second timing).
