Danfoss Actuator, PN 25, for SAVA, SAVD, 1 – 5 bar setting range, self-acting-controller spare (003H6846)

Danfoss actuator (003H6846) — 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 1 – 5 bar. OEM designation "Actuator PN25 1-4,5 SAVA,SAVD byp/ret/fl". Net weight 4.695 kg, gross 4.757 kg. Contains lead per the REACH candidate list. OEM P/N 003H6846. Technical data quoted verbatim from store.danfoss.com (code 003H6846). Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.

Compatibility

Genuine Danfoss actuator/adjustment-part spare (003H6846) for the SAVA, SAVD self-acting controller family, bypass / return / flow (per controller configuration). Match the controller type, mounting version and setting range (1 – 5 bar) to the valve body on site before ordering — the actuator top works and the valve body are ordered separately. Connects to the controlled/impulse pressure via Ø6 mm copper impulse tubes (compression fittings). Pressure class PN 25.
