Why VALSTEER Forged Steel Ball Valve?
Compact, high-pressure isolation with forged integrity and proven testing.
Forged for High Pressure
Forged bodies in ASTM A105 and stainless steels provide higher mechanical strength, refined grain structure and reduced porosity for demanding Class 800 to 2500 service.
Compact High-Pressure Design
Short face-to-face and small envelope dimensions make these valves ideal for tight piping layouts, skid packages and boiler rooms.
Reliable Shut-Off
Precision-machined ball and seats, blowout-proof stem design and robust packing deliver consistent tight shut-off under high differential pressure.
Multi-End Connections
Available with socket weld, screwed and butt-weld ends to match high-pressure piping specifications and maintenance preferences.
Standards-Compliant
Designed and tested in line with ASME B16.34, API 602 / API 598 and relevant end connection standards for project compliance.
Project Documentation Ready
Supplied with EN 10204 3.1 material certificates, pressure test reports and support for third-party inspection where specified.
