Hydraulic valve is the most commonly used system in industrial production, mainly used to control the flow direction of oil in the hydraulic system, but also can effectively adjust the pressure and flow. There are three kinds of hydraulic valves, namely pressure valve, direction valve and flow valve. For valves of the same shape, enterprises can choose different functions according to their different mechanisms of action. Although there are many kinds of hydraulic valves, there is always a basic common ground between these hydraulic valves. From the structure of the hydraulic valve, all hydraulic valves contain a valve body, spool and drive hydraulic spool action of the component, the component here mainly refers to the spring and electromagnet. In fact, the working principle of all hydraulic valves is the same, their opening size, the pressure difference between the inlet and outlet of the valve and the flow through the valve need to conform to a certain proportion, and all kinds of hydraulic valves can control their different parameters according to the actual needs. What requirements do hydraulic valves need to meet in actual work? Experts point out that the hydraulic valve must be sensitive, but also to do the use of reliable, working to minimize the impact and vibration, in addition, the pressure through the oil to minimize the loss, and the sealing performance is good. Compact structure is the most basic requirement of hydraulic valve, and maintenance, installation, adjustment and use is also very convenient, versatility is also strong.
