STIEBEL ELTRON Safety Group KV 40, for unvented water heaters

APPLICATION: Safety group for
pressure-resistant (closed) wall-mounted storage heaters
and under-sink small storage heaters 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,
backflow preventer and an
interchangeable diaphragm safety valve
with 0.6 MPa response pressure. The
overpressure safety valve prevents
exceeding the permissible
operating pressure of the hot water storage tank.
In addition, the safety group KV
40 is equipped with a pressure reducing valve
(pressure reducer). The
backflow preventer prevents the backflow
of heated drinking water into the
piping system. The
included funnel siphon with rosette
and connection accessories can be used to drain the
expansion water into the drain pipe.
FEATURES:
Pressure reducing valve, safety valve,
shut-off valve, backflow preventer,
funnel siphon, rosette, chrome-plated
connection accessories. INSTALLATION AND
SERVICE: The safety group KV 40
is simply installed according to the
specification design in front of the
hot water storage tank in the
cold water supply line. For quick
and easy maintenance, the
safety valve can be lifted by turning a knob.
The pressure reducing valve
according to DIN EN 1567 can reduce excessive
cold water inlet pressure to the
required system pressure.
In addition, the
cold water supply line of the subsequent
installation (e.g. a
hot water storage tank) can be closed via the
shut-off valve and
thus enables service-friendly
maintenance work. The components of the KV 40
are interchangeable. SAFETY AND
QUALITY: The safety group KV 40
consists of a high-gloss chrome-plated
brass housing, is manufactured with low lead content
and DVGW tested. The safety valve
is component-tested. The connecting pipes
consist of chrome-plated copper pipe. The
plastic parts comply with the
KTW recommendation. All materials are
designed and manufactured according to the recognized rules of technology.
