Transmission behaviour HE Heat exchanger transmission behaviourDepending on the construction, temperature spread, medium and hydraulic circuit, the power Q is not proportional to the water volumetric flow  (Curve 1). With the classical type of temperature control, an attempt is made to maintain the control signal Y proportional to the power Q (Curve 2). This is achieved by means of an equal- percentage valve characteristic curve (Curve 3).123Y www.belimo.comEP..R+MOD • en-gb • 2018-04-27 • subject to changes34EP..R+MODProduct featuresControl characteristicsCommunicative characterised control valve with sensor- operated flow control, 2-way, Internal thread, PN 16 (EPIV),
