Residential Comfort/Combustion : Hydronic Heating : Residential Heating Valves : VC6831 : VC6831AM1111/U
2-way 3/4 in Sweat VC Valve w/aux switch
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).
