Danfoss AFP 2 PN 16 self-acting differential-pressure controlling actuator — setting 0.1–0.35 bar, 640 cm² diaphragm, valve DN 65–250 (003G5611) — Datasheet

Danfoss AFP 2 PN 16 — a self-acting differential-pressure controller. It keeps the differential pressure across the controlled section constant by modulating the matching globe valve body via its rolling-diaphragm actuator, using the pressure signal fed to the actuator chambers. 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 640 cm²; setting 0.1–0.35 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 "AFP 2, PN 16, 0.1 bar - 0.35 bar, 640 cm²". OEM P/N 003G5611. Technical data quoted verbatim from store.danfoss.com (code 003G5611). 1.0345, zinc plated; diaphragm EPDM (Rolling, fibre enforced); Standard size: AFP 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.

AFP 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 (0.1–0.35 bar), actuator size (640 cm²) and the valve-body size range (DN 65–250). AFP(B) is the alternative-connection actuator variant of the same function; for pressure reduction use AFD; for pressure relief use AFA; for differential-pressure relief use AFPA. Confirm actuator size, setting range and matching valve body against the AF-range data sheet before ordering.
