Hydronic Design with Pressure Independent Control Valves

The pressure independent control valve will be examined as two valves within one body that separate the duties of controlling pressure variations within the hydronic system by way of a pressure controller – a form of pressure reducing valve – and a standard two-way control valve.  The advantages and disadvantages of designing with pressure independent control valves, as well as design considerations, will be addressed.  These will be highlighted utiilzing the same hydronic system from the initial presentation that addressed standard two-way control valves.
