4" Full Bore Flanged Ball Valve – ANSI Class 300

This DN100 (4") full bore flanged-end ball valve is designed for robust performance in industrial water, oil, and gas (WOG) systems. Rated for ANSI Class 300 (PN 50) pressure conditions, the valve offers reliable shutoff and flow control with a full bore passage to minimize pressure drop. The body is designated as “100G”, with either a 2-piece or 3-piece construction based on process requirements. Flanged ends conform to ASME B16.5 Class 300 standards, with raised face (RF) connections for secure installation. While the trim materials are not specified, markings such as “EP 305 DN 100” on end caps and “1.05” and “08 01” suggest manufacturing or quality control identifiers. Each unit is painted and labeled with stock tag “50.05” and carries a unique ordering number. This model is part of a lot of three identical valves visible in the same batch.
