Danfoss VFG 2 Flanged Globe Valve Body DN250 PN 16 Kvs 400 m³/h (2-Way flanged)

Danfoss VFG 2 two-way flanged globe (seat) valve body, OEM order code 065B2426. Nominal size DN250, pressure class PN 16, flow coefficient Kvs 400 m³/h. VFG 2 is the two-way district-heating/cooling control-valve body that combines with a matched self-acting (AFA/AFP/AFT/AVT) or electric (AMV/AME) actuator to form a pressure, temperature or flow controller. Grey cast iron EN-GJL-250 (GG-25) body with stainless-steel, mat. no. 1.4021 cone and stainless steel, mat. no. 1.4313 seat. Linear optimized flow characteristic. Stroke 24 mm, spindle normally open. Rated for district heating media at 2 °C to 150 °C, maximum differential pressure 10 bar. Data quoted verbatim from store.danfoss.com (code 065B2426).

Compatibility

Valve body for Danfoss self-acting / motorized control assemblies. Combine the VFG 2 DN250 body with a matched actuator (self-acting AFA/AFP/AFT/AVT or electric AMV / AME) sized for the required duty. Select the body by nominal size (DN250), pressure class (PN 16) and flow coefficient (Kvs 400 m³/h); verify actuator stroke 24 mm before ordering.
