Safety valve

A shut-off valve with safety valve ensures that
the product is not emptied if the supply of
cold water is stopped. The valve protects the
product from overpressure when the water
expands during the heating, by relieving the
pressure through the outlet. It is normal for
water to drip from the safety valve outlet
during operation. This must be taken into
consideration when the product is installed.
NOTE:
• The shut-off valve with safety valve does
not protect the product if the pressure in
the water pipe exceeds the specified
permitted pressure for the product.
• The shut-off valve with safety valve must
be cleaned and checked at regular
intervals to ensure that the product is
working properly and safely. The valve
must not be clogged or blocked. Any
scale must be removed.
