Danfoss VFGS 2 Steam Globe Valve Body DN50 PN 40 Kvs 32 m³/h (2-Way flanged)

Danfoss VFGS 2 two-way flanged globe (seat) valve body, OEM order code 065B2458. Nominal size DN50, pressure class PN 40, flow coefficient Kvs 32 m³/h. The VFGS 2 is the valve-body element of Danfoss steam 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. 1.4021 seat, linear optimized flow characteristic, 12 mm stroke, spindle normally open. Rated for steam at 2 °C to 350 °C, maximum differential pressure 20 bar. Data quoted verbatim from store.danfoss.com (code 065B2458).

Compatibility

Valve body for Danfoss steam control-valve assemblies. Combine the VFGS 2 DN50 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 (DN50), pressure class (PN 40) and flow coefficient (Kvs 32 m³/h); verify actuator stroke 12 mm and media compatibility before ordering.
