A hydraulic valve properly directs the flow of a liquid medium, usually oil, through your hydraulic system. The direction of the oil flow is determined by the position of a spool. A hydraulic system can only function - as per requirements - by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose.
Hydraulic valves are available in a variety of sizes. The size required is determined by the maximum flow of the hydraulic system through the valve and the maximum pressure in the hydraulic system. Hydraulic valves are available with different mountings: e.g. mounting in pipe lines, threaded connection as cartridges, sub plate mounting, etc.
Different Types of Hydraulic ValvesHydraulic valves are sometimes referred to as hydraulic components. These are subdivided into three main categories: directional control valves, pressure control valves and flow control valves. We also have proportional and servo control hydraulic valves.

Available in 9 different sizes, the large range of spools, spool operators, levers and auxiliary shock/anti-cavitation valves make this valves especially suitable for use in medium-complexity circuits. They are also very suitable for straight-forward applications in which a particularly small overall size is required.
This valves is available in the following versions: open centre, parallel/series, closed centre and carry-over.
A further notable feature is the very low level of internal spool leakage.
