Features & Benefits

Features and Benefits - Honeywell Pressure Limiting Valves

  • Pressures easily adjusted by simple loosening screw and turning knob.
  • Corrosion resistant DR (dezincification resistant) Brass with spring located outside the flow.
  • Integral filter and optimised flow path around the valve seat - valve is not sensitive to debris.
  • High quality synthetic valve seat - not sensitive to scaling.
  • Filter can be replaced and cleaned without removing valve from pipe work.
  • Constructed and noise resistance tested to German DVGW and UK WRc guidelines.
  • Can be used for water, other non-aggressive liquids, compressed air and for Nitrogen.
  • Complete with test ports for pressure gauge.
  • Hot water conversion available to maximum 70°C (with brass filter bowl fitted).

Features and Benefits - Honeywell Cold Water Expansion Valves

  • Energy saving valve - relieves cold water rather than hot, saving electricity
  • Forged, high quality, corrosion resistant DR brass body.
