Validation of our range of fire-safe capacitive ball sampling valve in compliance with the EN ISO 10497 standard


One of our client, a major petrochemical actor, asked us to adapt our capacitive ball sampling valve to fire-safe conditions.

Although long-term satisfied by our capacitive ball sampling valve, his QHSE department imposed that the new production line be fully fire-safe.

Our design department conducted a feasibility study and the Direction decided to invest in that project.

We qualified our valves with the certification body Lloyd’s Register and in compliance with the EN ISO 10497 standard.


Qualified sampling valves :

Capacity: 15 until 100ml

Dimension: DN10 to DN300

Pressure class: PN10 to PN40


Tested product : capacitive ball sampling valve in stainless steel DN50 150Lbs

Seats: PTFE

Body: graphite

Stuffing box: graphite


After carrying out successful tests, our valve complied with the EN ISO 10497 standard.

Our client is fully satisfied with this new range of fire-safe sampling valve which totally meets his requirements.


From then on, our range of capacitive ball sampling valves includes the fire-safe option.

We manufacture our sampling valves in various materials (SS 316LSS 304Luranustitaniummonelinconel, PFA or halar sheathed, PVDF…), different capacities, on liquid products, powdersgranulesgas...
