Procurement function is a strong optimisation lever of performances and competitiveness.

Generally speaking and not only within VALCO Group, this function is driven by the current acceleration of the Supply-Chain management. Structuring the supplier relationship to be more effective leads to the whole company efficiency.

While serving the different businesses and operating entities of VALCO Group, it also constitutes a development focus for the group’s activities, notably through the integration of ‘local content’ issues (some components purchases shall be made directly in the finished equipment country of destination).
In this context, the major missions are built around the following focuses:

  • Define a clear and consistent purchasing policy for the company, offering a high service level to its internal customers and supporting VALCO Group commitments in terms of responsibility (particularly concerning used materials’ origin and traceability);
  • Contribute to the creation of value by proposing appropriate sourcing to the different operating entities and integrating suppliers markets innovations and evolutions (materials, machining techniques …) ;
  • Promote procurement.

Production Process Overview

Working on the Lathe

  • Constant dialog with its customers
  • Customisation majorly related to piping and actuation of the valve

Sand Casting, Replicast / Rapidcast, Lost Wax

  • Dedicated and highly reliable suppliers for raw castings
  • Cleaning of raw castings using chemical liquids and blast cleaning technology
  • Machining is generally conducted in-house
  • Only valves >24” and weighting >1t are machined externally by local partners
  • Visual inspection and water pressure tests
  • Radiography and ultrasonic methods
  • Dye penetrant testing if requested

Stellite surface treatment ensures tight fitting of the seat into the valve

  • Unique assembling capabilities to install seating into the valve
  • Customised actuators are a key competitive advantage

Testing under extreme temperature and pressure conditions

Specific painting increases robustness and life of the valve
