2. PN 6 or 16
3. EN-GJL-250, JL 1040 or EN-GJS-400-18-LT, JS 1025
4. Straight-way and angle pattern
(angle pattern only EN-GJL-250)

6. Variant
*) For operating temperatures > 200 °C and uninsulated
valves please use the valve variant with high--temperature
resistant paint.
The valves meet the safety requirements of the Pressure
Equipment Directive 97/23/EC (PED) of annex I for fluids of
the groups 1 and 2.
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.
