Micro Hydraulic Valve

The commercially available model-hydraulic valves have advantages, but also disadvantages. The disadvantages have prompted me to develop a completely new design concept, which combines the advantages of the different conventional designs in itself. In conjunction with highest quality material a valve of superlatives is ensured:

The micro 4-port/3-way proportional-valve

manometer connection

Features

The mirco hydraulic valves are build modular. They can be stringed together in any number. Single modules can be added later.
Only the finest tool-steel with extremely high wear resistance is used.
A valve module is only 12mm wide.
A valve module has 4 ports. Up to 2 hydraulic cylinders can be connectied directly. No Y-connector is necessary.
The valve spool is 100% free of load. Therefore the necessary servopower is the same for 10bar or even 35bar.
The dynamic seal of the valve spool is at the pressure-less side. This avoids leakage. And the friction of the sealing is independent of the pressure.
The bore diameter is consistently 2.5mm. High flow rates with low friction is possible.
Valve tightness is independent of pump pressure. That means, the bucket will be hold for a long time.
all ports are M5
A sensitive activation of the valve follows a sensitive movement from the first stick move.
A rapid activation of the valve follows a rapid movement. Bucket rattling is guaranteed.
A pressure control valve 10-35bar is integrated.
A manometer connection M3 is integrated.

Hydraulic valve module with float position

A floating position is necassary for pulling an accurate formation level with bulldozers, groomers, tractor or wheel loader. Fixed blades intensify floor uneveness, because of the leverage between blade and chassis. Small ground waves are getting bigger.

The valve module with float position lets the Dozer Blade, die Levelling Bucket, den Front Ripper ot the AlpinFlexMill with Finisher slide freely over the formation level, independent from movements of the vehicule. Only in this way an accurate formation level is made fast.
