STIEBEL ELTRON Safety Group KV 30, for unvented water heaters

APPLICATION: Safety group for
pressure-resistant (closed) wall-mounted water heaters
up to 200 liters storage capacity according to DIN
1988, DIN 4753 and DIN EN 1488, up to
a supply pressure of max. 0.48 MPa
in the cold water line. The assembly
includes a shut-off valve,
non-return valve and an
interchangeable diaphragm safety valve
with 0.6 MPa response pressure. The
pressure relief safety valve prevents
the permissible operating pressure
of the hot water tank from being exceeded.
The non-return valve prevents
the backflow of heated drinking water into
the pipe network. The
expansion water can be discharged into the drain line
via the enclosed funnel trap with rosette
and connection accessories. EQUIPMENT:
Safety valve, shut-off valve,
non-return valve, funnel trap,
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 opened via 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 highly polished chrome-plated
brass housing, is manufactured with low lead content
and is DVGW tested. The safety valve
is component-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 according to recognized
technical standards.
