1 Product description Tapping valves 1.1 Design The tapping valves fabricated at Keulahütte GmbH should be used in conjunction with the appropriate elastomer for the fields of drinking water and gas. The operation is effected manually. The tapping process is performed with external tapping units and auxiliary valves. The series KH200 is available in different versions: KH200GR Clamp (1) without angle valve, with internal thread G¾ tog2 and external thread G2 2/1 KH210GR Complete cast clamp (1) with 2"outlet for APU tapping system KH220GR Clamp KH200GR (1) with brass angle valve with the outlets 11/4, 11/2, 2 KH221G as KH220GR but with the possibility of continuous rotation by 360 in 11/4 and 11/2 KH230GR Angle valve with integrated auxiliary shut-off ball with 11/2 outlet The actuation of the tapping valves is performed with the slider valve key C according to DIN 3223 on the mounting set. 1.2 Constructive parameters 1.2.1 Housing There are two options available for the housing It can be supplied complete with cast valve insert or as cast clamp with brass angle valve. The cast housing for KH210GR KH230GR is supplied in complete epoxy resin powder coating with a layer thickness of at least 250 μm For the tapping valves KH200GR, KH220GR, KH221GR and KH230GR, the cast clamp (1) is completely epoxy powder coated. The angle valve is made of brass or red brass and therefore requires no coating. 1.2.2 Valve insert The end cover (2) is a component formed by the parts 2.1 to 2.9 (see the parts list). A sliding disc (2.9) between the upper part (2.10) and the spindle (2.1) ensures low operating torques. The 6KT on the spindle (2.1) ensures an optimal torque transmission to the tappet (2.2).

1.2.3 Operating shut-off In the operation at the shut-off tappet (2.2) it is about a PTFE gasket (2.8) which is pressed for sealing against the sealing surface in the angle valve or in the housing. In order to use in the cast housing KH210GR an optimal sealing surface, a seat ring (3) is pressed in the housing (1), on which the PTFE gasket (2.8) makes the sealing. 1.3 Clamps systems For the tapping valves KH200GR to KH230GR various brackets variants are available. a) flexible stainless steel bracket for the Great-Range System (GR) system, a bracket per nominal width and type of pipe b) Bracket GR220: flexible wide area bracket A stainless steel bracket per nominal width for multiple pipe types 1.4 Function The tapping valves are operated in the OPEN-SHUT mode with the key C on the mounting set. Intermediate positions to make a regulation are not admitted. By pressing the mounting set that is tension-resistant connected to spindle (2.1), the spindle (2.1) and thus also the tappet is actuated (2.2). By turning counterclockwise, the tapping valve is opened (the tappet moves upward), and by turning it clockwise the valve closed (the tappet moves moves downwards).

The closed position is limited by the sealing seat in the angle valve or by the seat ring in the cast housings. When closing / opening the valve, a torque of 100Nm should not be exceed.

2 Maintenance and Installation manual 2.1 Mounting During the installation, after removal of the cap, attention should be paid to the cleanliness of the connection points and to ensure a tension-free mounting of the clamp (1) on the pipe. No damage to the pipe surface must exist on the area surrounding the tapping. If there are deep scratches, the drilling place must be shifted. After the straight placing of the fitting on the pipe, the bracket can be mounted and hand-tightened. It is important to ensure that the bracket gasket (4) is seated in its groove and does not slip out. Then tighten the nuts of the bracket evenly, alternately. The maximum tightening torque is 80Nm. The valve is tight already at much lower torques. Check the tightness of the clamp (1) around the outlet and on the pipe and tighten the nuts if necessary. When drilling the fittings, the instructions of the drilling device should be observed. 2.2 Maintenance The tapping valves are maintenance-free 3. Physiological safety for non-metallic installation components The declarations of harmlessness for the non-metallic parts used are available: - Rubber seals, O-rings (2.6, 2.7, 4) - PTFE gasket (2.8) - coated with epoxy resin powder coating (ESR) List of applicable standards for the tapping valves DIN EN 3543 DIN EN 1074-1 DIN EN 1074-2 DIN EN 1503-3 DIN EN 681-1 Tapping valves Valves for water supply Part 1 - General Requirements Valves for water supply Part 2 - Shut-off valves Valves Part 3 - Cast iron, that is specified in the European standards Elastomer Sealings Part 1 - Vulcanized rubber
