Danfoss SAVD safety pressure-reduction controller, PN 25, DN 15, kVS 4 m³/h, setting 2 – 8 bar, external thread G 3/4 A, free mounting (003H6969)

Danfoss SAVD (003H6969) — self-acting safety pressure-reduction controller, PN 25, DN 15, free mounting, for district heating and central-heating circuits. The SAVD is a self-acting safety pressure-reduction controller that requires no auxiliary energy: it reduces and limits the downstream pressure, closing on rising outlet pressure, using a control valve and a spring-loaded actuator diaphragm. As a safety controller (SAV pressure-reduction) it provides the self-acting overpressure protection required for district-heating substations, independent of any electric control. kVS 4 m³/h; adjustable pressure setting range 2 – 8 bar; maximum differential pressure 20 bar. Medium temperature 2–150 °C; leakage 0.02% of kVS (IEC 534); Valve body red bronze CuSn5ZnPb (Rg5), valve seat stainless steel 1.4571, valve cone dezincing free brass CuZn36Pb2As, actuator diaphragm EPDM. Connection external thread G 3/4 A (ISO 228/1). OEM P/N 003H6969, EAN 5710104031187. Technical data quoted verbatim from store.danfoss.com (code 003H6969).
