1.5 Valve approvals
Valve design is based on requirements by EN and ASME
standards.
Fire safety characteristics are defined according to API 607
and BS 6775.
A patent has been issued for the structure of the valve.
ATEX-classification: ATEX II 2G c.
1.6 CE marking
The valve meets the requirements of the European Direc-
tive 2014/68/EU relating to pressure equipment, and has
been marked according to the Directive.
1.7 Recycling and disposal
Most valve parts can be recycled if sorted according to
material. Most parts have material marking. A material list is
supplied with the valve. In addition, separate recycling and
disposal instructions are available from the manufacturer. A
valve can also be returned to the manufacturer for recycling
and disposal against a fee.
