Product Description
The A400 maintains a pre-set maximum flow rate regardless of upstream pressure variation. A flow control pilot measures differential pressure across an integral orifice and modulates the main valve to limit flow to the set value. Used to prevent excess draw from transmission mains, control bulk meter bypass flows and protect distribution networks from demand surges.
