Product Description

The integrated manual ball valve features a one-piece forged body that eliminates external leakage. The straight-through, zero dead-leg flow path ensures linear media passage with no retention or cross-contamination. A triple-seal stem design with patented anti-leak structure provides reliable long-term sealing. Mirror-polished internal surfaces meet high-purity requirements, while the full-bore ball channel minimizes flow resistance. Fully degreased for liquid cooling circuits.
