Danfoss VG Control Valve Body DN 20 PN 25 Kvs 6.3 m³/h (2-Way threaded)

Danfoss VG two-way threaded seat (globe) control valve body, OEM order code 065B0775. Nominal size DN 20, pressure class PN 25, flow coefficient Kvs 6.3 m³/h. The VG 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. Red bronze, mat. 2.1096.1 (RG5) body with DZR brass CuZn36Pb2AS (CW 602N) cone and stainless-steel, mat. 1.4571 seat, approx. linear flow characteristic, 5 mm stroke, spindle normally open, piston pressure relief. Rated for district heating/cooling circulation water at 2 °C to 150 °C, maximum differential pressure 20 bar. Connection G 1 A (ISO 228/1). OEM P/N 065B0775. Data quoted verbatim from store.danfoss.com (code 065B0775). 2.1096.1 (RG5); cone DZR brass CuZn36Pb2AS (CW 602N); seat Stainless steel, mat. 1.4571; Standard size: DN 20; Thread: ISO 228/1; Pressure rating: PN 25 (25 bar); max differential pressure 20 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. No. No.

Compatibility

Valve body for a Danfoss district heating control-valve assembly. Combine the VG DN 20 body with a matched electric AMV / AME (or self-acting) actuator sized for the required duty. Select by nominal size (DN 20), pressure class (PN 25) and flow coefficient (Kvs 6.3 m³/h); verify actuator stroke 5 mm and media compatibility before ordering.
