Danfoss Lower actuator adjustment part, PN 25, for SAVA, SAVD, 3 – 11 bar setting range, self-acting-controller spare (003H6848)

Danfoss lower actuator adjustment part (003H6848) — genuine PN 25 spare assembly for the Danfoss self-acting controller range. It is the diaphragm actuator / setting-spring "top works" that mounts on the controller valve body: the actuator senses the controlled differential pressure through the Ø6 mm copper impulse tubes and modulates the valve cone, and the adjustment part carries the setting spring that fixes the working range. Fits Danfoss SAVA, SAVD controllers, bypass / return / flow (per controller configuration). Adjustable setting range 3 – 11 bar. OEM designation "Low.Act.Adj.part PN25 3-11 SAVA-D". Net weight 4.623 kg. OEM P/N 003H6848. EAN 5702421553039. Technical data quoted verbatim from store.danfoss.com (code 003H6848).
