APPLICATION:
Safety group for pressure-resistant (closed) wall storage and over-table small storage according to DIN 1988, DIN 4753 and DIN EN 1488, up to a supply pressure of max. 0.48 MPa in the cold water supply line. The assembly includes a shut-off valve, backflow preventer and a replaceable 0.6 MPa diaphragm safety valve. The overpressure safety valve prevents the permissible operating pressure of the hot water tank from being exceeded. In addition, safety group KV 40 is equipped with a pressure reducing valve (pressure reducer). The backflow preventer prevents the return of heated drinking water to the mains. The expansion water can be discharged into the drain line via the provided funnel siphon with rosette and connection accessories.
EQUIPMENT: Pressure reducing valve, safety valve, shut-off valve, backflow preventer, funnel siphon, Rose, chrome-plated connection accessories.
INSTALLATION AND SERVICE:
The KV 40 safety group is simply installed in the cold water supply line in accordance with the specification before the hot water tank. For quick and easy maintenance, the safety valve can be ventilated via a rotary handle. The pressure reducing valve in accordance with DIN EN 1567 can reduce a too high cold water inlet pressure to the required system pressure. In addition, the cold water supply for the subsequent installation (e.g. a hot water tank) can be closed via the shut-off valve and thus enables service-friendly maintenance work. The components of KV 40 are interchangeable.
SAFETY AND QUALITY:
The safety group KV 40 consists of a high-gloss chrome-plated brass housing, is made of lead-poor and DVGW tested. The safety valve is part-tested. The connection pipes are made of chrome-plated copper pipe. The plastic parts comply with the KTW recommendation. All materials are designed and manufactured in accordance with the recognized rules of technology.
