Fuchslocher Complete Assemblies

Using genuine Fuchslocher shut off units all Invotec shut off nozzles are manufactured to our exacting standards.

How they work  

In the off state (zero pressure) the needle is in the forward position meaning the outlet bore is closed. This is achieved with the pre-clamped spring, which forces the pressure over the bridge to the needle.

If the dynamic pressure or injection pressure overcomes the spring-stress the nozzle opens automatically. The spring-pressure closes automatically if the specific injection pressure reduces.
