Danfoss VGF two-way flanged seat (globe) control valve body, OEM order code 065B0785. Nominal size DN 50, pressure class PN 25, flow coefficient Kvs 25 m³/h. The VGF is the valve-body element of a Danfoss district heating control-valve assembly: it pairs with a matched electric AMV / AME (or self-acting) actuator to form a temperature, pressure or flow controller. Ductile cast iron EN-GJS-400-18-LT (GGG 40.3) body with DZR brass CuZn36Pb2AS (CW 602N) cone and stainless-steel, mat. 1.4571 seat, approx. linear flow characteristic, 10 mm stroke, spindle normally open, piston pressure relief. Rated for district heating/cooling circulation water at 2 °C to 150 °C, maximum differential pressure 16 bar. Connection 50 (EN 1092-2). OEM P/N 065B0785. Data quoted verbatim from store.danfoss.com (code 065B0785). 1.4571; Standard size: DN 50; Pressure rating: PN 25 (25 bar); max differential pressure 16 bar; Temperature range: 2 °C to 150 °C; Approval: CE; Approvals: CE; HS code: 8481.80. Deployed in process, utility and marine piping loops for on-off shutoff, control, safety relief or diversion service.
