The standard applies to refrigerant pressure regulating valves controlling volatile refrigerant flow whose primary response is to pressure.

AHRI White Paper:
A Look into Flow & Contaminant Control Products Section Standards

Section Scope

The section is open to manufacturers of solenoid valves; 2-, 3-, 4-way reversing valves; thermostatic, electronic and automatic expansion valves of all capacities; temperature and pressure regulating valves, which function alone or in combination with other controls or sources, that are designed primarily for the purpose of automatically controlling refrigerant flow (liquids or gases) or the flow of fluids supporting the refrigeration cycle in refrigeration or air-conditioning systems.

All manually operated valves used to control the flow of refrigerant or flow of fluids supporting the refrigeration cycle.

Sealed filter-driers having solid core desiccant, loose-fill desiccant, or a combination of the two; replaceable core filter-driers for use in liquid or vapor refrigerant lines; sealed or replaceable element suction filters; cores or elements for shells; receiver driers; strainers; and liquid or moisture-liquid indicators. These products alone or in combination are intended for use primarily in refrigeration or air conditioning systems for the purpose of detecting and/or removing system contaminants.

Excluded from all of the above are devices used with:
  • Automotive and recreational vehicle air conditioning
  • Domestic refrigerators/freezers, and Individual room air conditioners not included in the scopes of AHRI air-conditioning product sections
  • Hydronic system flow control valves that are included in the scope of the AHRI Hydronics Section
