ITIS | Valve World 2022: Düsseldorf Germany

It was great to be back at Valve World 2022 with Luc Vernhes (Velan) to present the new standard ISO 23632 and our ITIS experiences regarding Design Validation Testing on valves.

ISO, API & EN are the three dominant standard organizations for industrial valves and provide procedures to assess performance during hydrotest, fire test and fugitive emission test. However, missing from these existing standards was the ability to gauge the durability of a valve, from shut-down to shut-down, or the total number of mechanical cycles the valves can perform for batch processes.

This is the reason why ISO 23632 was developed, a new standard to assess seat performances and torque requirements through mechanical and thermal cycles. Valve performance is typically measured during testing, either in production or in a laboratory setting.

Roughly 60% of the valves do not comply with DVT requirements. Some valves fail under conditions (pressure, temperature, operational cycles) they will be exposed to in the field and therefore are not fit for their purpose. This could be a major cause for concern.
