Скачать или смотреть Roquet monoblock hydraulic control valve line - 2017

This line stated operation in 2016 with four machining centres, automatic high-pressure cleaning, 3D measurement and 2-stage precision honing.

The target market was for monoblock valves for construction machinery. Initially 3-spool valves were produced.

As the quantity of 6-spool valves increased it became clear that two additional machining centres were needed, which were installed early 2017.

The capacity on this line is now 150,000 precision bores per year to 20mm diameter. Tolerance held is about 1 micron which permits rather low leakages.

Grooves are machined to give good spool timing and all valves are 100% hydraulically tested - including pressure settings, leakage rates, pressure drops, etc.
