Introduced in 1979 by the Daniel Valve Company, the Dan-Ex dual expanding plug was designed to improve the integrity for double block and bleed valve applications. The engineered valve was designed as an improved version of the General Twin Seal Valve. Design improvements include a solid carbon steel plug, one piece camshaft, and large diameter plug trunions.

Dan-Ex valves are currently manufactured in Western Valve’s state of the art manufacturing facility in Bakersfield, CA. Thousands of Dan-Ex valves have been installed in pipelines, liquid terminals, and aviation fueling operations worldwide since its introduction in 1979. The widespread use of the Dan-Ex valve is a result of its superior design and manufacturing quality.
