Features

A rugged, Class 800 forged steel ball valve designed to withstand extreme pressures and thermal shock in critical petrochemical lines.

✅Forged A105 Construction: Unlike standard Cast Iron Ball Valves which can be brittle, the forged A105 body eliminates porosity and defects, offering exceptional tensile strength for high-pressure/temperature safety.

✅High Pressure Rating (Class 800): Engineered to handle working pressures up to 2000 PSI (Class 800), making it far superior to standard PN16 valves for steam traps, hydraulic lines, and high-pressure gas isolation.

✅3-Piece Bolted Body: The heavy-duty 3-piece design allows for inline maintenance (swing-out capability) and easy seat replacement without removing the entire valve from the pipeline, reducing downtime.

✅Fire-Safe Design: Built in compliance with API 607 standards, featuring a secondary metal-to-metal seat that ensures a seal even if the primary soft seat is destroyed by fire—critical for refinery safety.

✅Blowout-Proof Stem: Features a bottom-loaded stem that cannot be blown out by internal pressure, providing maximum safety for operators working near high-pressure lines.
