safety release valves are used to protect the
systems from over pressures in the gas trains
in the event of sudden overpressures due to closure of
So that the
when the line is charged with over pressure than the set
pressure, it will allow the release of gas from
the system and it is recommended to leave the vent line
from this valve safely outside of the building.
available in sizes of only 1" and
the pressure setting is available from 20 mbar
to 1000 mbar using different set of springs as per
maximum allowable inlet pressure of the gas is 1 bar.
Popular model is FRSBV 1010.
APQ Safety Release Valves
safety release valves can be used for the same
purpose as mentioned above.
made by APQ Spain.
available in sizes of ½" and 1" and setting

in the system, this valve will shut the gas in
the pipeline and prevent the down stream system from the
damage due to over pressure.

maximum allowable Inlet pressure of gas as 6 bar and
shut off setting pressure range between 80 to 550 mbar.
APQ Slam Shut Off Valve
available in two different versions :

APQ Tower Gauge
Gauge is available in the size of ½" NPT
having multifunction like facility for
connecting the pressure gauge, impulse lines from
regulator and slam shut off valve.
push button cock for this tower gauge is bitable,
allowing you to see the pressure in the gauge while
setting the pressure on the regulator.
special feature is that we can
rotate the pressure gauge after fitting the
same by 360 degrees without leakage of gas or
loosening of pressure gauge.
