4 CONTROABE CHECK VAVES EA 4 Appliction The controllble check vlves EA offer simple n effi cient protection ginst pollution of the drinking wter supply system. These protection devices prevent bckfl ow of polluted wter from fl owing bck into the drinking wter supply system (fl uid clss 2). The check vlve's function nd tightness cn be tested without the need for disssembly. Controllble EA check vlves cn be used both in domestic nd in other pplictions. Stndrdiztion The controllble check vlves EA hs been developed in conformity with EN1717. Instlltion instructions Instll the check vlves EA ccording to ntionl instlltion instructions. EA Specil chrcteristics Kiw, DVGW, NF nd/or BEGAQUA pprovls Complies with CEN Stndrd EN Sfety clss EA Very low resistnce ong life Hmmer free opertion Noise free opertion or plstic Connection unions Model The check vlve consists of: Brss body with test nd drin ports nd connection unions s required Plstic check vlve module ipsel seling principle Split vlve stem Width rnge DN 15 - DN 65 Connection sizes 1/2" to 3" or 15 mm to 67 mm Fields of ppliction iquids potble wter Opertion The pressure of the liquid fl owing in presses the vlve ginst the torpedo, creting n opening. The ptented split vlve stem gurntees motion-free guidnce between the vlve nd the torpedo. When the liquid pressure drops, the vlve is closed ccording to the ipsel seling principle. 1. Vlve open. 2. Initil closing. 3. Totl closure. This ipsel seling principle works s follows: 1. Vlve open. iquid pressure keeps the vlve open. 2. Initil closing. Without counter pressure, the vlve pushes the diphrgm outwrd, lredy seling the inlet. 3. Totl closure. The diphrgm is pushed outwrd completely by the vlve. The counter pressure pushes the diphrgm fl ush ginst the vlve, thus seling the inlet completely. Other models Refer to the tble on pge 5 for the vrious models.

5 CONTROABE CHECK VAVES EA Opertion split vlve stem Under certin conditions, e.g. fl ushing the toilet t night, vibrtions cn occur s consequence of the vlve stem being ble to move sidewys. The split shpe of the vlve stem, however, gurntees mximum guidnce. Vibrtions re prevented by combining n optimum fl ow profi le nd split vlve stem. 5 Resistnce grph for EA check vlves Pressure difference [kp] , Flow [l/min] Approximte vlues, precise curves per vlve on request. ine check vlve no. type 1 BB015 KF015 2 BB020 KF020 S015 WF015 3 BB025 KF025 S020 WF020 4 BB032 S025 WF0025 S032 WF032 5 BB040 S040 WF040 6 BB050 S050 WF050 Assembly Assemble the EA check vlve fter the wter supply system hs been clened in the prescribed wy. Instll the EA check vlve in front of the dngerous pplince. This prevents polluted wter from fl owing bck into the drinking wter system. In conformity with the ntionl instlltion instructions, stop cock must be plced in front of the EA check vlve.

Exchnging or clening dirty or dmged check vlve crtridge is now mtter of simple hndling. For the DN 15 en DN 20 besides the isoltion vlve on the inlet side, pressure guge nd drin vlve, second isoltion vlve hs been integrted into the outlet side. It prevents the drinking wter instlltion downstrem the CC 55.1 from drining during mintennce nd replcement. The DN 25 with 28 mm compression fi tting hs been developed specilly for instlltion in front of fi re reel. There is lredy n isoltion vlve in front of the fi re reel. For this reson the CC 55.1 DN 25 hs only been given n isoltion vlve t the upstrem side. Depending on your ppliction, you might lso order the bsic model CC, check vlve without pressure guge nd drin vlve. Stndrds The CC 55.1 nd CC re developed in conformnce with EN1717.
