Danfoss AFD 2 PN 16 self-acting pressure-reducing actuator — setting 0.1–1 bar, 320 cm² diaphragm, valve DN 65–250 (003G5632)

Danfoss AFD 2 PN 16 — a self-acting pressure-reducing controller (pressure reducer). It keeps the reduced (downstream) pressure constant by modulating the matching globe valve body via its rolling-diaphragm actuator. The actuator carries the diaphragm and setting spring only; it combines with a Danfoss VFG 2 / VFGS 2 / VFU 2 globe valve body (ordered separately) to form a complete self-acting controller for district heating and district cooling circuits. Actuator diaphragm area 320 cm²; setting 0.1–1 bar; suits valve bodies DN 65–250. Media temperature 2 °C to 150 °C; maximum operating pressure 16 bar. Actuator housing Steel, mat. 1.0345, zinc plated; diaphragm EPDM (Rolling, fibre enforced). Medium: district heating/cooling circulation water (glycolic water up to 30%). OEM designation "AFD 2, PN 16, 0.1 bar - 1 bar, 320 cm²". OEM P/N 003G5632. Technical data quoted verbatim from store.danfoss.com (code 003G5632). 1.0345, zinc plated; diaphragm EPDM (Rolling, fibre enforced); Standard size: AFD 2; Pressure rating: PN 16; Temperature range: 2 °C to 150 °C; HS code: 8481.90. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants. No.

Compatibility

AFD 2 is the self-acting actuator of the Danfoss AF range; it combines with a Danfoss VFG 2 / VFGS 2 / VFU 2 globe valve body to build a complete controller. Select by pressure class (PN 16), required setting range (0.1–1 bar), actuator size (320 cm²) and the valve-body size range (DN 65–250). For differential-pressure control use AFP; for pressure relief use AFA; for flow limitation use AFQ. Confirm actuator size, setting range and matching valve body against the AF-range data sheet before ordering.
