The Festo VHER-AH-M04E-G14-LD is a solenoid-operated 4/2‑way valve designed to control compressed air in automation circuits. It has four ports and two positions, enabling direction control of a pneumatic actuator by routing air to either side of a cylinder. As a Festo component, it is built for integration within standard pneumatic systems and provides automated switching via electrical energization of the coil.
