Methods and Precautions for Use

Z030-Z031 and Z035 CE-marked ball valves meet the requirements of PED Directive 2014/68/EU and/or ATEX Directive 2014/34/EU.

1) All standard Z030-Z031 and Z035 valves can be used in a temperature range of -10°C to +150°C.

For different temperatures, the valve should be equipped with seals made of material suitable for the required operating temperature.

2)All standard Z030-Z031 and Z035 valves are not equipped with devices against internal overpressure, such devices as balance hole or etched seat are available upon specific request from the end user.

3) All standard Z030-Z031 and Z035 valves in general, do not accept the presence of ice and fluids subject to instability inside the valve, as they would block the OPEN or CLOSE maneuvers, in addition, the increase in fluid volume can damage the valve components making it no longer usable.

4) Standard Z030-Z031 and Z035 valves can be used at low temperatures (from -29°C and down to -196°C for cryogenic service) or at high temperatures (up to +250°C). Any requirements must be agreed upon by the customer with the sales department when ordering/offering.

5) Z030-Z031 and Z035 valves can be used for "industrial" oxygen use only if thoroughly degreased and packed in special bags. Medical use, if any, should be specified when ordering/bidding.
