Product Overview
The SWAGELOK 6LVV-DPFR4-P is a high-purity pneumatic diaphragm valve engineered for precision fluid control in demanding industrial and process environments. Manufactured by Swagelok, a globally recognized leader in fluid system components, this valve utilizes a flexible diaphragm as the sealing and actuating element, isolating the working fluid from the valve’s internal actuation mechanism. This design eliminates packing, stem seals, and wetted dynamic seals, making it ideal for applications requiring leak-tight shutoff, contamination-free flow paths, and reliable performance in high-cycle pneumatic and process control systems. The 6LVV-DPFR4-P is a normally closed (NC) configuration, actuated by an external pneumatic supply, and is specifically suited for integration into gas delivery panels, analytical instrumentation, and high-purity process lines.
