The V8043E1020 from Honeywell is a 1” Sweat Zone Valve w/ End Switch, 18” leads. It consists of a motorized actuator and valve assembly for controlling the flow of hot water to a heat exchanger such as a radiator, convector, finned baseboard radiator, or infloor radiant coil for space temperature control. The V8043 5000 series valves provide two-position, straight through control of supply water at up to 300 psi operating pressure.


  • Hydronic Control. Use this valve in closed loop hydronic systems that do not contain dissolved oxygen in system water, such as fresh water from frequent source of makeup water.
  • Valve designed for cycling (not constantly powered on) applications;


  • Manual opener (on all models, except straight-through, normally open valves) for valve operation on power failure
  • valve returns to automatic position when power is restored
  • Compact construction for easy installation
