[ABOUT COMPANY]

Founded in 1986, DK-Lok Corporation is a fitting & valve manufacturer of S. Korea. With global supply of innovative products, we became a leading brand in many applications, such as oil & gas, NGV, Hydrogen FCEV, and semiconductor UHP. As our top priority on customer satisfaction, digital transformation is under way with a goal to establish smart factory at workshop. SPC (Statistical Process Control) is our primary tool for the highest quality control. In particular, we introduce two new products, One is Diaphram valve weldments and the other is Regulators at this exhibition.
