We have been involved in the production of turbine valves from the very beginning – it is one of the key products of Metal Expert. Years of technical knowledge, appropriate production equipment, and qualified personnel are the essential foundation for manufacturing this product. In the production of turbine valves, we are not limited by any special processes, and we ensure comprehensive delivery.

Valves assembly

We provide comprehensive services for the pre-assembly and main assembly of valves.

During assembly, depending on the valve’s construction, press-fit components are either cooled in liquid nitrogen or heated in a furnace to ensure uniform heating of the part. In collaborating valve parts that serve the closing function, the stroke is examined, and then the sealing surfaces undergo a lapping control to check their alignment.

Assembled elements are tightened with the required torque values and secured with appropriately selected adhesives from Loctite or welded to prevent loosening during operation.

Valve components include items such as guides, screens, pins, sealing elements, washers, threaded components, spindles, closures (locks), diffusers, sleeves, and more.

Our standard valve components are typically within the size of Ø800×2000, but we can handle larger sizes as well.
