Danfoss VFQ 2 two-way flanged globe (seat) valve body, OEM order code 065B2682. Nominal size DN50, pressure class PN 40, flow coefficient Kvs 32 m³/h. VFQ 2 is the flow-limiting valve body (function "Pressure relief", product group "Pressure flow controllers"): combined with a matched self-acting AFQ actuator, or an AFQ / electric AMV / AME actuator, it forms a flow limiter or flow controller. GS-C 25 body with stainless-steel, mat. no. 1.4404 cone, linear optimized flow characteristic, 12 mm stroke, spindle normally open. Rated for district heating media at 2 °C to 200 °C, maximum differential pressure 20 bar. Data quoted verbatim from store.danfoss.com (code 065B2682).

Valve body for Danfoss flow-limiter / flow-controller assemblies. Combine the VFQ 2 DN50 body with a matched self-acting AFQ actuator (flow limiter) or an AFQ / electric AMV / AME actuator (flow controller) 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.
