APPLICATION: Safety group for pressure-resistant (closed) wall storage tanks with a storage capacity of up to 200 liters in accordance with DIN 1988, DIN 4753 and DIN EN 1488, up to a maximum supply pressure of 0.48 MPa in the cold water pipe. The assembly includes a shut-off valve, non-return valve and a replaceable diaphragm safety valve with a response pressure of 0.6 MPa. The overpressure safety valve prevents the permissible operating pressure of the hot water tank from being exceeded. The backflow preventer prevents the backflow of heated drinking water into the mains. The expansion water can be discharged into the drain pipe via the enclosed funnel siphon with rosette and connection accessories. EQUIPMENT: Safety valve, shut-off valve, non-return valve, funnel siphon, rosette, chrome-plated connection accessories.INSTALLATION AND SERVICE: The KV 30 safety group is simply installed in the cold water supply line before the hot water tank according to the specification design. For quick and easy maintenance, the safety valve can be lifted using a rotary handle. In addition, the cold water supply line of the subsequent installation (e.g. a hot water tank) can be closed via the shut-off valve, thus enabling service-friendly maintenance work. The components of the KV 30 are interchangeable. SAFETY AND QUALITY: The KV 30 safety group consists of a high-gloss chrome-plated brass housing, is made with little lead and is DVGW tested. The safety valve is component-tested. The connecting tubes are made of chrome-plated copper tubing. The plastic parts correspond to the KTW recommendation. All materials are designed and manufactured according to the recognized rules of technology.
