Class 2500 Welded Bonnet Globe Valve

Product Overview

The  Class 2500 Welded Bonnet Globe Valve is engineered for ultra-high pressure and temperature environments. Featuring a securely welded bonnet design, it eliminates leak paths common in bolted joints, ensuring maximum safety and zero emissions under severe conditions.

Forged for optimal grain flow and structural integrity, this compact globe valve provides precise throttling and bi-directional tightness. It is the definitive choice for critical isolation and regulation in high-pressure steam lines, power generation plants, oil refineries, and severe-service petrochemical applications.
