WebWhen control valve selection is critical or when the circuit is subjected to major changes in ΔH, a local differential pressure controller can stabilise the differential pressure across the control (Fig 4a). This is generally the case when the control valve authority can drop below 0.25. The principle is simple. Webof the pump is proportional to the number of two way valves being closed. It will bypass the differential pressure created by the pump as the zone valves close, thus eliminating water hammer noise.
