Product Overview
The SMC VEX3702-124DZ is a high-performance 3-port pneumatic power valve engineered by SMC Corporation, a global leader in pneumatic and industrial automation technology. This valve operates as a direct-acting, solenoid-piloted directional control component designed to manage compressed air flow with exceptional precision and repeatability. As part of the VEX series, it is specifically engineered for high-flow applications requiring rapid response and reliable switching in automated industrial systems. The 3-port configuration (normally closed, 2-position) makes it ideal for pressurizing and exhausting single-acting actuators, blow-off circuits, and vacuum switching applications. Its robust construction and compact design allow seamless integration into manifold assemblies and standalone pneumatic control panels, ensuring optimal performance in demanding manufacturing environments.
