*) 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.
