Excavator Pipe-Rupture Valve CFS

Description

The excavator pipe-rupture valve is used wherever so required by the standards ISO 8643, EN 474 and DIN 24093 for excavators with a lifting device (e.g. a load hook on the bucket). The actuators concerned are the lift cylinder, the stick cylinder and the adjusting cylinder.

Advantages

- fulfills safety requirements in accordance with ISO 8643, EN 474 and DIN 24093
- leak-free load holding
- compact design → very low weight
- satisfies exacting demands on corrosion protection → valve is zinc plated (Cr VI-free)
- the control assembly is guaranteed to close → it closes even with a broken spring
- no impact, or only very low impact on the existing hydraulic system → easy to retrofit
