SMC VNC311B-F20A-5DZ-B-X184 Pneumatic Solenoid Valve

SMC VNC311B-F20A-5DZ-B-X184 is a two-port process coolant valve from SMC’s VNC series that is solenoid-operated and externally piloted to precisely control coolant flow in machine-tool circuits. It is designed for switching coolant paths in tool-machine environments, relying on an external pilot signal generated by the solenoid to shift the main valve. The VNC family supports a range of port and seal configurations, with typical port sizes from 1/8 to 2 Rc(PT) and seal materials including NBR, FKM, and EPR, enabling compatibility with diverse coolants and operating conditions. As an externally piloted valve, it can be integrated with SMC manifolds and standard pneumatic plumbing to deliver reliable actuation in automated tooling setups, making it suitable for CNC machines, milling centers, and other metalworking equipment where precise coolant control is essential. The VNC line is crafted for compact installation within coolant circuits, offering straightforward mounting and dependable performance in industrial environments.
