Danfoss AFQMP 2 DN 200 PN 16 pressure-independent flow + differential-pressure control valve — flange, Kvs 650 m³/h, flow 36–450 m³/h, Δp 0.1 bar–1 bar

Danfoss AFQMP 2 DN 200 PN 16 — self-acting pressure-independent flow control valve with an integrated differential-pressure controller, for district heating and district cooling circuits. Combines automatic flow limitation, a control valve and a differential-pressure controller in one body: the flow set point is held independent of pressure variation, while the differential pressure across the control valve is kept constant. Flange connection. Kvs 650 m³/h; adjustable flow range 36–450 m³/h (flow restrictor differential pressure dpb 1 bar); differential-pressure setting range 0.1 bar–1 bar. Media temperature 2 °C to 150 °C. Maximum operating pressure 16 bar. Body Grey cast iron EN-GJL-250 (GG-25); valve cone and seat Stainless steel mat. No. 1.4021; EPDM seals and rolling diaphragm. Normally-open stem, stroke 28 mm. Medium: district heating/cooling circulation water (glycolic water up to 30%). OEM designation "AFQMP 2, PN 16, DN 200, 0.1 bar - 1 bar, Flow rate [m³/h]: 36 - 450, Flange, Mounting version: Free". OEM P/N 003G5565. EAN 5714279064759.
