Pressure Sustaining, Circulation and Relief in Irrigation Systems — Your Questions Answered
In a recent BERMAD webinar, “Pressure Sustaining, Circulation and Relief in Irrigation Systems”, our Application Engineer Sarit Hatzbany took a closer look at pressure sustaining principles of operation and the key differences between relief, circulation and inline sustaining valves.
When we need to limit the flow using hydraulic methods (as opposed to electronic methods), the flow is not continuously measured & sampled (only during setting). Therefore, pilots are designed to hydraulically sense the differential of pressure or force/velocity associated with the varying flow.
