Item Features
  • Anti-scale with visual system pressure indicator.
  • Automatic fast-filling - Fast fills the system to set pressure then automatically shuts off the water feed, no levers to flip or valves to close.
  • Maintains stable pressure at pre-setting - Fill the system to a set pressure and maintain that pressure setting regardless of inlet pressure variations.
  • Anti-scale polymer materials - Prevents scaling on internal sliding surfaces, assuring stable pressure control and long operating life.
  • Built-in shut-off valve and check valve - Allows isolation of system from supply and check valve prevents loss of system pressure if the supply water drops below system pressure.
  • Pre-calibration - Before charging the system, use a screwdriver to turn dial to intended system pressure, downstream pressure gauge is not required.
