Product Overview
The SWAGELOK 6LV-DFL11345-P-BL is a high-purity, pneumatically actuated diaphragm valve engineered for precision flow control in demanding industrial and process environments. Manufactured by Swagelok, a global leader in fluid system components, this valve utilizes a flexible diaphragm as the sealing element, isolating the working fluid from the valve actuation mechanism to prevent contamination and ensure leak-tight shutoff. The 6LV series designation indicates a 6mm (1/4 in) line size with a spring-return pneumatic actuator, while the “DFL” configuration denotes a diaphragm valve with a flow-through body design. The “-P-BL” suffix specifies a pneumatic (air-to-open) actuator with a black nylon-encapsulated solenoid pilot or position indicator, depending on the exact configuration. This valve is specifically designed for critical applications requiring high cycle life, minimal dead volume, and exceptional cleanliness, making it ideal for analytical instrumentation, semiconductor manufacturing, and high-purity gas delivery systems.
