Pressure reducer

Ø 1/2' 0.5-6 Bar

Assy: AT7-0006-FF0

Technical parameters:

A pressure-reducing valve equipped with a pressure gauge, adjustable to achieve an outlet pressure within the range of 1 to 6 bar.


Its primary purpose is to maintain a consistent and safe pressure level downstream, regardless of the incoming pressure to avoid an overpressurized system which can activate the safety valve and cause leaks or damage the water system components.


The housing is made of chrome-plated brass, and both the cartridge and dirt trap are removable for easy maintenance.

  • Factory setting: 3 bar
  • Maximum operating temperature: 80 °C
  • Pressure gauge scale: 0 to 10 bar
  • Operating medium: water
  • Connections size - 1/2"


We suggest using it with all AUTOTERM combiBOIL systems!
