Blackstone valve programs begin with a free inspection and proposal, giving you a clear understanding of your options before making any decisions. Wir reparieren Verdichterventile aller Marken und Typen, from every major brand, always applying manufacturer-based best practices and procedures. Our precision machining approach removes less material from each valve, extending service life and allowing for more maintenance cycles over time. Partnering directly with Baker Hughes and Cozzani, we follow the latest OEM procedures to restore valves to current design specifications—delivering as-new performance with full compliance and traceability. To ensure reliability in service, Blackstone applies advanced testing methods. Our Cozzani flow bench provides detailed leakage reports, while standard solvent leak testing is available based on customer-specific requirements. This flexibility allows us to accurately evaluate and test a wide range of valve types.

Blackstone offers complete valve lifecycle support, including: 

With proven experience across all major valve brands, we deliver the expertise and OEM relationships you can trust.
