Forged Steel Check Valve

ASME 150-2500

This range of ASME Class 150 to 2500 reduced bore forged steel valves offers flexibility with screwed, socket weld, butt weld, or flanged ends. Designed for demanding applications, these valves are ideal for systems that require reliable, leak-tight performance under high temperature and pressure conditions.

Applications include vents, drains, by-pass systems, instrument isolation, control valve isolation, auxiliary steam lines, heat exchangers, and oil and gas applications.
