New safety valve
for opening pressures
less than 0.5 bar
The AV619 safety relief valve from Witt Gas
Techniques Ltd, UK, is a new spring loaded,
direct acting safety relief valve for venting
excess gas pressure from receivers,
pipelines and other equipment used in the
chemical and oil processing industries.
Supplied with a TÜV pressure-setting
certificate, this new safety valve provides
a sensitive opening pressure from 5 mbar
up to 500 mbar. A high relieving capacity
is also possible due to the large cross
section of the valve opening. It is also able
to work in a temperature range of -40°C to
approximately +300°C.
This new safety relief valve, which can
be used with all technical gases, is an
addition to the existing range of relief
valves available from Witt Gas Techniques.
It is available in either brass or stainless
steel and has a range of inlet and outlet
connections to suit. An adaptor is also
available for connection to a ventilation
pipe.
Depending on the connection, the flow
capacity can range from 2.6m3/hr to 90.7m3/
hr, whilst the setting pressure pe ranges
from 5-500 mbar.
The valve seat seal material is dependent
on the gas being used and specified at the
point of order. These valves are compact in
size for easy installation and every valve is
100 per cent tested by Witt Gas Techniques
before leaving the factory.
