The virtuous circle of quality

Our customers’ requirements in terms of quality as well as the normative pressure, (more particularly the full traceability from the raw material batch to the final product, PMI test), have been a great opportunity to deeply change our practices and set apart from our counterparts. This logic also led us to more cleanliness and safety for our staff and more respect for the environment.

“The system of quality and environmental management at Guichon Valves is certified according to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018.  More than just a certification however, it is a real management tool used daily whether it be determining objectives per department, tracking the results of steering meetings or implementing and monitoring continuous improvement.

GUICHON VALVES assures full traceability of its products through its ERP system and work procedures.  At any given moment, all the details of a valve sub-assembly can be identified and we can determine the material used, on which machine it was produced and by which operator.”.
