Because of the high temperatures that canbe associated with solar collectors, this valve has theability to withstand the most demanding conditions.The thermostat can operate with boiling point hotwater and yet it still has the reaction performance tomaintain the required set temperature.This valve will not only handle high temperaturesassociated with solar heating, but doubles as a highperformance HP tempering valve and is ideal foruse on instantaneous hot water systems or underconditions where fluctuating supply pressures areexperienced.Warning4,55These valves must not be dismantled. Servicing shouldbe restricted to inspecting the inline check valves forcorrect operation and cleaning the strainers.1012Ø 15 mm14161820Ø 20 mm15 mm Kv= 1,5 (m 3 /h)20 mm Kv= 1,7 (m 3 /h)2530G (l/min)35404550COLDCodeABCDEFDFED*E*A* Only for 252219Technical DataMIXED252212 252219ø15ø2062.56912513891126.548.58442.542.5Temperature rangeTemperature controlMaximum hot inlet temperatureMaximum working pressure (static)Maximum working pressure (dynamic)Minimum working pressure (dynamic)Maximum unbalanced dynamic supplypressures (hot/cold or cold/hot)Minimum temperature differential betweenhot water inlet and mixed water outlet toensure shutoff functionMinimum flow rate for stable operationBCAS 4032.2WMKA 02466Specifications are subject to change without notice.ABA35-50˚C+/- 3˚C100˚C1400kPa500kPa20kPa6:110˚C4 l/minHOTDISTRIBUTED BYAll Valve Industries Pty Ltd30/205 Port Hacking Road Miranda NSW 2228www.allvalve.com.auAS4032.2WMKA 02466© June 2008
