Oil & Gas
Zero-Leakage Isolation in Hydrocarbon Service
Oil & Gas facilities face demanding conditions – high pressures, sour media, and nonstop production. Vestra Valve’s SG-1 line is engineered with rocket-applied chromium-carbide seating, robust mounting brackets, and in-line repairability to deliver dependable, long-life service in the harshest energy environments.
Applications:
• Offshore production systems
• Midstream crude and gas transport
• Gas dehydration and compression
• Utility isolation and emergency shutdowns
Why Vestra for Oil & Gas: At Vestra, every valve is machined, coated, assembled, and tested in Houston, Texas. Owning the full process means tighter quality control, faster response when replacements are needed, and valves that live up to their promise. In Oil & Gas, failure is never an option; and with Vestra, it isn’t.
