This concept is explained in more detail in BSRIA BG 51 [1]. A linear characteristic causes an increase in flow that is directly proportional to the degree of valve opening. It is used for the bypass port on three-port control. An equal percentage characteristic is so called because as the valve opens, for each percentage increment in valve travel (linear and rotary movements), the flow increases by an equal percentage. It is used for terminal devices.’	+	[https://www.bsria.com/uk/product/BKMxLn/test_method_for_picvs_and_dpcvs_bts_12019_a15d25e1/ Test Method for PICVs and DPCVs (BTS 1/2019)], published by BSRIA in November 2019, defines flow characteristic as: ‘The relationship between the flow through a valve and its degree of opening.
