Danfoss Actuator & adjustment part, PN 25, for AVPQ, 0.2 – 1 bar setting range, return mounting, self-acting-controller spare (003H6833)

Danfoss actuator & adjustment part (003H6833) — 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 AVPQ controllers, return (controller installed in the return pipe). Adjustable setting range 0.2 – 1 bar. OEM designation "Act. & adj.part PN25 0,2-1,0 AVPQ return". Net weight 2.442 kg. Contains lead per the REACH candidate list. OEM P/N 003H6833. EAN 5702421552810. Technical data quoted verbatim from store.danfoss.com (code 003H6833).

Compatibility

Genuine Danfoss actuator/adjustment-part spare (003H6833) for the AVPQ self-acting controller family, return (controller installed in the return pipe). Match the controller type, mounting version and setting range (0.2 – 1 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.
