4 Installation Valve mounting Before valve mounting the pipes have to be cleaned and free from abrasion. Valve must be mounted according to flow direction as indicated on valve body. Mechanical loads of the valve body caused by the pipes are not allowed. Valve should be free of vibrations as well. Installation of the valve with the actuator is allowed in horizontal position or upwards. Installation downwards is not allowed. A AB A AB B Mixing Fig. 1: Mixing or diverting connection B Diverting Fig. 3: Mixing valve used in diverting application Fig. 2: Mixing valve used in mixing application Fig. 4: Diverting valve used in diverting application Mixing or diverting connection 3-way valve can be used either as mixing or diverting valve (fig.1). If 3-way valve is installed as mixing valve meaning that A and B ports are inlet ports, and AB port is outlet port it can be installed in mixing (fig.2) or diverting application (fig.3). 3-way valve can be also installed as diverting valve in diverting application (fig.4) meaning that AB port is inlet and A and B ports are outlets. Note: Only valves DN are suitable for diverting installation. Maximal closing pressure for mixing and diverting installation are not the same. Please refer to values stated in Technical data section. Disposal The valve must be dismantled and the elements sorted into various material groups before disposal. 4 VD.LS.D5.02 Danfoss 11/2011 DEN-SMT/SI
5 Sizing Flow Rate (liquid with specific a gravity of 1) l/sec m 3 /h Δp max FLOW Pressure drop kpa (100 kpa = 1bar = ~ 10 m H 2 O) Example Design data: Flow rate: 6 m 3 /h System pressure drop: 55 kpa Locate the horizontal line representing a flow rate of 6 m 3 /h (line A-A). The valve authority is given by the equation: p1 Valve authority, a = p1+ p2 Where: Δp1 = pressure drop across the fully open valve Δp2 = pressure drop across the rest of the circuit with a full open valve The ideal valve would give a pressure drop equal to the system pressure drop (i.e. an authority of 0.5): if: Δp1 = Δp2 a = Δp1 2 Δp1 = 0,5 The intersection of line A A with the diagonal lines gives the pressure drops stated by real, rather than ideal, valves. In this case, a valve with k VS 6,3 would give a pressure drop of 90,7 kpa (point C): 90.7 hence valve authority = = The second largest valve, with k VS 10, would give a pressure drop of 36 kpa (point D): 36 hence valve authority = = Generally, for a 3 port application, the smaller valve would be selected (resulting in a valve authority higher than 0.5 and therefore improved control). However, this will increase the total pressure and should be checked by the system designer for compatibility with available pump heads, etc. The ideal authority is 0,5 with a preferred range of between 0,4 and 0,7. In this example an authority of 0,5 would be given by a valve having a pressure drop of 55 kpa at that flow rate (point B). The intersection of line A A with a vertical line drawn from B lies between two diagonal lines; this means that no ideally-sized valve is available. DEN-SMT/SI VD.LS.D5.02 Danfoss 11/2011 5
