Product Overview
The SWAGELOK 6LV-DPFR4-P-C is a high-purity pneumatic diaphragm valve engineered for precision fluid and gas control in demanding industrial and process environments. Manufactured by Swagelok, a global authority in fluid system technology, this valve utilizes a flexible diaphragm as the sole moving wetted component, isolating the actuation mechanism from the process media. The 6LV series designation indicates a VCR metal face-seal fitting configuration with a 1/4 in. tube size, while the DPFR4 code identifies a pneumatic, normally closed (spring-return) diaphragm valve with a PCTFE (polychlorotrifluoroethylene) diaphragm and a 4-series actuator. The “P” suffix denotes a pneumatic actuator, and the “C” suffix indicates a normally closed (NC) configuration. This valve is purpose-built for ultra-high-purity (UHP) semiconductor, pharmaceutical, and analytical instrumentation applications where contamination control, leak integrity, and repeatable actuation are paramount.
