Typical applications are:Lubrication Systems, Shaft-Sealing OilSystems, Fluid Power Filtration Systems -Fluid Power Heat Exchange Arlon s continuous - flow transfervalve design guarantees shock-freeuninterrupted flow while simultaneouslydivertering both inlet and outlet flowsfrom one component to its twin, withoutaltering the continuity of full flowthrough the valve.

2 A tight shut-off of theidle component is provided to allow foreasy maintenance. Parker Arlon ballvalves do a leak-free, efficient job in awide variety of applications for fluids, andprocess media. (fig. 1)MountingEnsure the balls are aligned in parallelwith the couplingshaft when the change-over lever is against the stop on thedetention plate. When fitting valves , careshould be taken to ensure they are notsubjected to any extreme loads appliedvia heat exchangers or associated valve connections should never beexposed to torsional stresses of any kind. Springloaded ball -Seat DesignThe absolute tightness of the Parker Arlon3-way 2-seat flanged ball valves isobtained by the floating ball designwhich gives an automatic, positive jacks or locking flanges are notnecessary. To guarantee leakfree functioning underthe most severe system-circumstances,the valves are provided with twospringloaded glass fibre reinforced PTFE ball seats one in port 'A' and one inport 'B', resulting in an extremely lowchange-over torque at equalizedpressure.

3 As there is no ball seat mounted on port'C' it is avoided that this port will be shutoff (see valve torque data). (fig. 2)Stem Seal DesignThe stem seal design consists of a radialand axial glass fibre reinforced PTFE bushing with a PTFE back-up ringprotected double "O"- ring sealingconstruction. (fig. 3)Equalizing LineBefore changing over, the pressure in thesystem has to be equalized to avoidpressure shocks and air locks.

5 During storage the ball valve should besealed against the entry of contaminant,which may cause damage to the balland Ensure that the change-over lever isplaced against its stop on the detentionplate to protect the seals of Transfer ball Valveswith Flexible Coupling shaftEnsure the balls are aligned in parallel withthe couplingshaft when the change-overlever is against the stop on the detentionplate. When fitting valves , care should betaken to ensure they are not subjected toany extreme loads applied via heatexchangers or associated vessels. The valveconnections should never be exposed totorsional stresses of any kind. If operational pressures exceed 5 bar thevalves should be pressure equalized priorto change-over ( valves with integratedequalizing lines or separated equalizinglines between vessels should be used).Ensure flanges are square when of Transfer ball valves ,Single or Rigidly CoupledEnsure the balls are aligned in parallelwhen the change-over lever is against thestop on the detention plate.

6 When fittingvalves, care should be taken to ensure theyare not subjected to any extreme loadsapplied via heat exchangers or associatedvessels. The valve connections shouldnever be exposed to torsional stresses ofany kind. If operational pressures exceed 5bar the valves should be pressureequalized prior to change-over (valveswith integrated equalizing lines orseparated equalizing lines between vesselsshould be used). Ensure flanges are squarewhen operate change-over ball valves ,pressure must be equalized on both sidesof installation and all free air expelled fromsystems. This prevents excessive loadsbeing applied to change-over levers andairation of system fluid. Change-over iscarried out as follows:1. Open vent valve unit not in service;2. Open equalizing line;3. Close vent valve when all free air hasbeen expelled from system;4. When pressure has equalized, valve canbe changed over in one singlemovement of change-over lever (90 turn L-bore and 180 turn T-bore).

On completion of change-overequalizing line must be hrend der Lagerung und desTransports sollen die Anschl e derArmatur abgedichtet dein, damit keineunerw nschten Fremdk rper in dieAnschl e eindringen k nnen. Gleichzeitigmuss darauf geachtet werden, dass derSchathebel gegen Anschlag gesetzt der Doppeldreiwege-Wechselkugelh hne mit Kupplungs-gest nge und WellengelenkenDie Parker Arlon Wechselkugelh hnem ssen so montiert werden, dass dieAnschlagscheiben gegen bergestellt sindund mittels der Kupplungsgest ngesgesichert werden. Bei der Montage derWechselkugelh hne m ssenaussergew hnliche Spannungen auf dieArmatur vermieden werden. Die Anschl e d rfen auf keinen Fall aufTorsion belastet werden und die Flanschem ssen in gerader Linie stehen. DerSchalthebel soll immer gegen denAnschleg gestellt werden. Ist derArbeitsdruck h her als 5 bar, so muss - bevor eine Umschaltung erfolgen kann -ein Druckausgleich der Doppeldreiwege-(starrgekuppelt) und Einfachdreiwege-Wechselkugelh hneDiese m ssen so montiert werden, dassder Schalthebel die Anschlagscheibesichert.

Der Umschaltvorgang sollwie folgt ausgef hrt werden:1. Die in Betrieb zu setzende System-H lfteentl ften;2. Die Ausgleichsleitung ffnen;3. Entl ftungshahn schliessen, nachdemdas System entl ftet ist;4. Den Wechselkugelhahn mit einerBewegung umschalten bis zumAnschlag (leichter Schlag 90 GradDrehung f r T-bore und 180 GradDrehung f r L-bore);5.
