Overview

The SJ400X flow control valve holds delivery to a fixed maximum rate, preventing excessive draw-off and ensuring fair distribution across a network. The hydraulically actuated main valve responds to a differential-pressure pilot across an orifice, modulating to keep flow constant as system conditions change.
