1. Description
Series D1FV proportional pressure reducing valves are available with and without onboard electronics (OBE).
D1FV OBE
The digital onboard electronics are situated in a robust metal housing, which allows the usage under rough environmental conditions. The nominal values are factory set. The cable for connection to a serial RS-232 interface is available as an accessory.
D1FV for External Electronics
The parameters can be saved, changed and duplicated in combination with the digital power amplifier PWD00A-400. The value parameters can be edited with the common ProPxD software for both versions. The D1FV values control the pressure in the A- or B-ports using the barometric feedback principle
