Distributing valves are used in an open circulation. They provide various consumer loads with the delivery flow of the pump. The distributing valves of ALPHAFLUID are available in mono design or modular circuit board. The valves with electrical resp. electronically proportional control don’t need any additional control pressure supply. The hydraulic auxiliary energy for the build on input unit is taken from the main oil circulation and will be lead towards the triggered consumer load via the moved distributor valve.

Advantages:

• Solid construction
• Low weight
• No additional control pressure supply
• Parallel operation possible
• Shock absorbing action of the distributor valve that is smooth switching on-
  and switching off of the consumer loads
• Flexible modular design (modular circuit board)
• Excellent sensitivity due to electronic proportional operation
• Add-on kit for directional valves

The linear unit is a proportional cylinder including integral position control which means any position may be achieved. It will remain there irrespective of external powers.

Advantages:

• No additional control valves needed
• No electronics needed
• Very solid construction
• Steady-state less than 0.5 %

The hydraulic 3-way-switch is a logic valve which works automatically. It solves with little energy the problems of long hydraulics pipe lines, works as a return flow relief or as a rapid traverse valve. In the usage of hydraulics the 3-way-switch is also called 3/2-way-switch, however without any external operating units. Shown is the simple construction including a few components. The automatical control can be clearly seen and the two switching positions will always be attained.

Advantages:

• Installation of pipes or cartridge available
• Direct installation in the cylinder base or -head possible
• Oil replacement in long pipes
• Rapid traverse circuit
• Return flow relieve

Various aspects have to be taken into consideration when dealing with the dimensioning of containers of fluidity circuits. As a result there will be no failures or problems during later operation. An important factor is the rotate time of the medium. Problems concerning the air- and dirt precipitation will occur should the rotate time be too short or the size of the tank too small. This will result in frothing, dirt dispersion, stream flow murmur and cavitation of the pump exhaust.

The diffuser of AlphaFluid enables you to use smaller containers by avoiding the mentioned problems. The diffuser enormously decelerates the oil speed of the return flow pipe. As a result the marginal exit speed of the tank leads to a smooth mixture of the return flow medium with the medium contained in the container.

Function:
The medium of the return flow pipe is split up in a lot of component currents. It will be radially decelerated within each of the component currents. The practical construction allows an exact adjustment to the requirements. Only by changing the screens, can the number of the component currents be determined. The diffusers made of steel or stainless steel are hard- wearing against mechanical loads and maintenance-free.

Advantages:

• Smaller tank possible
• No return pressure
• No cavitations any more
• Improved air- and dirt precipitation
• No dispersion of dirt in the tank
• Noise reduction
• Maintenance-free
• No oil foam formation

A familiar problem occurs - most common are inches or metric threads. The design engineer or mechanic of hydraulic systems always faces the same problem. He has to connect the equipment with different threads safe and water-tight. If he tries to solve this problem with the usual standard screwing, combinations of different screwing will occur. Thus the costs will be raised and the reliability of the system is diminished.

Therefore AlphaFluid offers a variety of more than 250 special purpose screwing. It includes metric and inch threads in different designs. All screwing is designed at the screw in side with a metal water- tight edge. Thus a lot of common problems can be avoided such as seal tolerance, too high or too low operating temperature, sealing service life regarding the surface roughness of the thread counter sink. This variety of screwing will be constantly enlarged and adjusted to the arising requirements.

Advantages:

• Sealing edge out of metal - Standard
• Conversion from inches into metric and vice versa
• Reducing of leaking points
• Available from stock
• Customer specific sizes

Through the oil fine filters very small particles up to 0.5 µm² are filtered and water is adhered. By using the filter, the purity level according to ISO 4406: 12/5- NAS 1638: 3 is achieved. As a result the oil change intervals can be extended many times.

Advantages:

• Little abrasion of machines and power units
• Reducing of the operating expenses
• Reducing of downtimes
• Environmental- and resource friendly
