SMC VM430-01-01S Vacuum Ejector

SMC VM430-01-01S is a compact, manual-control valve from the VM400 family that provides direct, roller-lever actuation for a 3/2 pneumatic circuit (three ports: P, A, R; two positions). The unit uses Rc1/8 port connections and is rated for a maximum operating pressure of 1 MPa, making it suitable for precise, hands-on control of small actuators or vacuum devices in tight automation spaces. As a VM430 variant, the valve is designed for non-electrical actuation in compact systems and aligns with standard VM400 mounting patterns and fittings. Orientation guidance advises mounting with the roller lever facing upward to ensure full travel and repeatable actuation, a consideration when integrating into panels or manifolds. The model is commonly used to manually switch air to a pneumatic actuator or to a vacuum ejector line in constrained installations, delivering reliable, power-free control without electronics or noise.
