Your Valve Authority is XXXX, ideally valve authority should be between 0.5 and 0.7 but never less than 0.3
Authority is generally expressed by the symbol "N" where:
P1 = pressure drop across the valve fully open
P2 = pressure drop in remainder of the circuit, valve fully open
A typical circuit is shown diagrammatically below. In order to maintain reasonable control without undue pressure drop the value of "N" should be ideally between 0.5 and 0.7 but never less than 0.3.
