Type 5413 is a pilot operated 4/2-way solenoid valve with manual override as standard. A 3/2-way solenoid pilot valve allows control. The valve consists basically of two assembled 3/2-way valves for ports A and B with a counter built-in servo piston with seat seals. Through pilot channels, the servo piston is operated at the input pressure and pushed either apart or towards the valve centre. A minimum pressure difference of 1 bar is required for switching.
