Stiebel Eltron 238957 KV 30 safety group

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 supply pressure of max. 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 storage tank from being exceeded. The non-return valve prevents the backflow of heated drinking water into the pipe network. The expansion water can be drained into the drain pipe via the enclosed funnel siphon with rosette and connection accessories. EQUIPMENT: Safety valve, shut-off valve, backflow preventer, funnel siphon, rosette, chrome-plated connection accessories.INSTALLATION AND SERVICE: The KV 30 safety group is simply installed in the cold water supply line in front of the hot water tank in accordance with the specification design. The safety valve can be opened using a rotary handle for quick and easy maintenance. In addition, the cold water supply line of the subsequent installation (e.g. a hot water tank) can be closed using 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 manufactured with low lead and is DVGW tested. The safety valve is component-tested. The connecting pipes are made of chrome-plated copper pipe. The plastic parts correspond to the KTW recommendation. All materials are designed and manufactured in accordance with recognized technical standards.
