Danfoss VFG 2 Globe Valve Body DN150 PN 40 Kvs 280 m³/h (2-Way flanged)

Danfoss VFG 2 two-way flanged globe (seat) valve body, OEM order code 065B2421. Nominal size DN150, pressure class PN 40, flow coefficient Kvs 280 m³/h. The VFG 2 is the valve-body element of Danfoss district heating / cooling control-valve assemblies: 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. Cast steel GP240GH (GS-C 25) body with stainless-steel, mat. no. 1.4021 cone and stainless-steel, mat. no. 1.4313 seat, linear optimized flow characteristic, 24 mm stroke, spindle normally open. Rated for district heating/cooling circulation water at 2 °C to 150 °C, maximum differential pressure 12 bar. Data quoted verbatim from store.danfoss.com (code 065B2421).

Compatibility

Valve body for Danfoss district heating / cooling control-valve assemblies. Combine the VFG 2 DN150 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 (DN150), pressure class (PN 40) and flow coefficient (Kvs 280 m³/h); verify actuator stroke 24 mm and media compatibility before ordering.
