Danfoss VFG 33 Three-Way Mixing Globe Valve Body DN125 PN 25 Kvs 160 m³/h (3-Way flanged)

Danfoss VFG 33 3-way flanged globe (seat) valve body, OEM order code 065B2613. Nominal size DN125, pressure class PN 25, flow coefficient Kvs 160 m³/h. The VFG 33 is a three-way mixing valve body (flow-dividing / flow-mixing service, function "Pressure relief" plus "Mixing valve", control ratio 1:50). It pairs with a matched self-acting (AFA / AFP / AFT / AVT) or electric (AMV / AME) actuator to form a temperature, pressure, differential-pressure or flow controller. Ductile cast iron EN-GJS-400-18-LT (GGG 40.3) body with stainless-steel, mat. no. 1.4404 cone and stainless-steel, mat. no. 1.4021 seat, linear flow characteristic, 20 mm stroke, spindle a-ab: normally closed. Rated for district heating media at 2 °C to 200 °C, maximum differential pressure 10 bar. Data quoted verbatim from store.danfoss.com (code 065B2613).

Compatibility

Valve body for Danfoss three-way mixing control-valve assemblies. Combine the VFG 33 DN125 body with a matched self-acting (AFA / AFP / AFT / AVT) or electric (AMV / AME) actuator sized for the required duty. Select the body by nominal size (DN125), pressure class (PN 25) and flow coefficient (Kvs 160 m³/h); verify actuator stroke 20 mm and media compatibility before ordering.
