Anti-Blowout Stem in Ball Valves: Safety Design and Selection Guide
Learn why anti-blowout stems are an essential safety feature in industrial ball valves. The guide explains how an internally retained stem design prevents pressure-driven stem ejection, how floating and trunnion ball valves can incorporate stem retention, and what buyers should verify through cross-section drawings, applicable API or ISO standards, fire-safe requirements, pressure-temperature ratings, material records, and inspection documentation.
