Description
  • Valve designed for cycling (not constantly powered on) applications.
  • 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.
Two-way on-off low voltage valves consist of an actuator and valve assembly for controlling the flow of hot water.
  • 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.
  • All models may be installed without disassembling the valve.
  • Compact construction for easy installation.
  • Complete powerhead may be removed or replaced without breaking plumbing line connections or draining the system.
  • Actuator motor may be replaced without removing the valve body or draining the system.
