PED 97/23/EC
The valves do not have a potential internal source of ignition
and can be used in potentially explosive atmospheres,
group II, category 2 (zones 1+21) and category 3 (zones
2+22) according to ATEX 94/9/EC.

Installation instructions
Observe direction of flow and integral direction arrow.
For opening, a minimum pressure is required. If this pressure
is not attained, the installed closing spring can be removed.
Valves without a closing spring can only be installed upright in
horizontal pipelines.
