Hydraulic valves direct the flow of a liquid medium and regulate the fluid line in hydraulic systems. The valves determine the flow of the fluid thanks to the position of a spool. This system can not function if there are no valves to regulate the flow. Choosing the right hydraulic valve is essential and a critical process when it comes to hydraulic systems so that`s why there are correct types of hydraulic valves to serve a particular purpose.
Also hydraulic valves have different sizes and shapes and to choose the right size, first you need to take into consideration the maximum flow of the hydraulic system. Besides that we determine the type of valve depending on the maximum pressure in the system as well. The valve is one of the most important parts that maintain the pressure and the flow – be careful when picking up one.
As we already mentioned there are so many different types of hydraulic valves (we usually call them hydraulic components). We divided them into 3 main categories: Direction control valves, pressure control valves and flow control valves. There are also sub-divisions of these categories.
All valves are different and they all function in a variety of ways. The directional control valve – passes on the pressure. The check valves – allow free flow in one direction. Pressure control vales – switch when particular pressure is applied.
Check out the video below and find out how all these types of hydraulic valves work. The video explains everything! Remember that all the valves have different names so, don’t get confused!
