2.6 PRODUCTION AND ACCEPTANCE

P/N 5220, 5320 and 5321 ball valves are manufactured and accepted in accordance with:

PN-EN 12266-1: 2012 (Industrial valves. Testing of valves. Pressure tests, test procedures and acceptance criteria.

Mandatory requirements). All valves (100%) are subject to tightness testing. The tests include external body

tightness and closure tightness. The valve closure performance and tightness are tested for both medium flow

directions at low and high pressure vales. The tested valves shall be free of any leaks, according to the closure

tightness class A per PN-EN 12266-1:2012.

The markings of valves are specified in the standards: PN-EN 19: 2005, PN-EN-1074-1: 2002.

Each valve carries a name plate located on the body flange and reading:

ball valve type (specified as the standard number applicable to the product);

- nominal diameter;

- nominal pressure;

- sealing temperature rating,

- manufacturer's company name and logo;

- product serial number,

- year of production;

- the Polish Construction Mark "B" and the CE mark;

- manufacturer's trade mark.

3 PROTECTION, STORAGE & TRANSPORT

All outer surfaces of the valve body, except for the interface surfaces of TYPE 5220 & 5320 flanged valves

and TYPE 5320 valve welded end surfaces are preserved with a RAL 1023 coat.

The anti-corrosion coating layer minimum thickness is 150µm.

The part surfaces are pre-treated for epoxy coating in accordance with the relevant Technical File and PN-EN ISO

12944-5: 2009.

The details e.g. the disc springs on TYPE 5320 & 5321 and the screw plug on

TYP 5220 are protected against corrosion by hot-dip galvanizing per PN-EN ISO 1461:2011. The protective

coating minimum thickness is 50µm.

The TYPE

5220, 5320 & 5321

with heat-shrunk film.

The valves shall be stored packaged and in dry rooms that are sheltered from weather and protected from

corrosive substances.

The valves shall be transported in sheltered vehicles and protected against damage. Handle and transport

heavy ball valves on strap slings (an example of which is shown in the diagram below).
