Valves
Electrically operated process and media valves
Festo electrically operated process and media valves control liquids, gases and steam in industrial processes via electromagnetic actuators. The MN1H, VZWM, VZWD, VZWF and VZWP series cover 2/2-way switching functions for port sizes from G 1/4 to G 2, designed for compressed air, water, oils and neutral gases. The M22C coil versions across the VZW series allow tool-free coil replacement in the installed position.
