According to EN ISO 7396-1, the valve box is equipped with the physical unsealing. For this purpose
the relevant shut-off valve must be closed, the pipeline behind the valve should be emptied. Then,
physical cut-off may be unscrewed and screwed in again after the works.
For the emergency supply, NIST connectors should be used. They are encoded for the given
gas. NIST connectors together with the pressure reducer should be mounted on the emergency bottle
with compressed gas, placed in proper socket, pushing it in and screwing down the pin cap. Before
opening of the valve of the bottle, it is required to loosen reducer’s hand wheel. After slow opening
of the valve of the bottle the pressure on the reducer may be set as per working pressure in the instal-
lation.
6. Maintenance / repair
Each valve box must be subjected to maintenance at least once a year. In particular, it is re-
quired to check the shut-off valves and points of emergency supply and check the tightness of the
pressure connections inside the box. Any repairs may only be performed by a qualified personnel.
