Danfoss SAVA safety pressure-relief controller, PN 25, DN 32, kVS 12.5 m³/h, setting 2 – 7.5 bar, external thread G 1 3/4 A, bypass mounting (003H6963)

Danfoss SAVA (003H6963) — self-acting safety pressure-relief controller, PN 25, DN 32, bypass mounting, for district heating and central-heating circuits. The SAVA is a self-acting safety pressure-relief controller that requires no auxiliary energy: it opens on rising pressure to relieve the circuit, using a control valve and a spring-loaded actuator diaphragm. As a safety controller (SÜV pressure-relief) it provides the self-acting overpressure protection required for district-heating substations, independent of any electric control. kVS 12.5 m³/h; adjustable pressure setting range 2 – 7.5 bar; maximum differential pressure 16 bar. Medium temperature 2–150 °C; leakage 0.05% of kVS (IEC 534); Valve body ductile iron EN-GJS-400-18-LT (GGG 40.3), valve seat stainless steel 1.4571, valve cone dezincing free brass CuZn36Pb2As, actuator diaphragm EPDM. Connection external thread G 1 3/4 A (ISO 228/1). OEM P/N 003H6963, EAN 5710104031125. Technical data quoted verbatim from store.danfoss.com (code 003H6963).
