Description
The SMC VNB series are high-performance process valves designed for industrial automation applications requiring precise flow control. These 2-port valves are engineered to handle a wide variety of fluids including air, water, oil, and vacuum. Featuring a cylinder actuation mechanism with external pilot air, they offer reliable switching performance even in demanding environments. The compact design and versatile mounting options make them suitable for integration into complex fluid control systems.
