Ball valves are provided with casted marking according to requirements of PN-EN19 standard. The marking facilitates technical
identification and contains:
diameter nominal DN (mm),
pressure nominal PN (bar),
body material marking,
arrow indicating medium flow direction,
manufacturer’s mark,
heat date,
CE marking, for valves subjected 2014/68/UE directive. CE marking starts from DN32
2.
REQUIREMENTS FOR MAINTENANCE STAFF
The staff assigned to assembly, operating and maintenance tasks should be qualified to carry out such jobs. If the valve is provided
with mechanical actuators, operating manual of actuator should be obeyed.
3. TRANSPORT AND STORAGE
Transport and storage should be carried out at temperature from –20
0
to 65
0
C, and valves should be protected against external forces
influence and destruction of painting layer as well. The aim of painting layer is to protect the valves against rust during transport and
storage. Valves should be kept at unpolluted rooms and they should be also protected against influence of atmospheric conditions.
There should be applied drying agent or heating at damp rooms in order to prevent condensate formation. The valves should be
transported in such a way to avoid hand lever and valve stem damage.
It is not allowed to fit lifting devices to connecting holes.
