Product Overview
The SMC VY1200-02N-X39 is a precision electro-pneumatic proportional valve engineered by SMC Corporation, a global leader in pneumatic and industrial automation control technology. This valve operates on a direct-acting, solenoid-driven proportional principle, where an electrical input signal (voltage or current) proportionally modulates the internal spool position to deliver infinitely variable flow control of compressed air or neutral gases. Unlike standard on/off directional valves, the VY1200 series provides continuous, analog-style regulation of flow rate, making it an essential component in closed-loop pneumatic control systems requiring precise force, speed, or pressure modulation. The “X39” suffix denotes a specialized factory configuration, typically involving specific electrical connector, seal, or performance characteristics tailored to demanding industrial environments. Its compact 02-size body and robust construction make it ideal for integration into manifold assemblies and modular pneumatic circuits.
