Hydraulic Parts Supplier Near Me

With the continuous improvement of China's hydraulic pump production technology, China's hydraulic parts industry has become an industry with a professional production system and complete production categories. There are many types of hydraulic parts, in the large market environment, multi-brand and multi-series products, the quality is inevitably uneven, what principles need to be followed when selecting various hydraulic components in the hydraulic system? I believe that there will be some troubles for friends who are new to the hydraulic industry, so the following is a brief introduction by Elephant Fluid Power for you.


  1. Selection of hydraulic pump

    Hydraulic pump specifications and models according to the calculated value in the product sample selection, in order to make the hydraulic pump work safe and reliable, hydraulic pump should have a certain pressure reserve, usually the rated pressure of the pump can be 25%-60% higher than the working pressure. The rated flow rate of the pump should be comparable, not more than too much, so as not to cause excessive power loss.

  2. Selection of flow valve

    When selecting throttle valves and speed regulating valves, it is also necessary to consider whether their minimum stable flow meets the design requirements, generally the minimum stable flow of medium and low pressure flow valves is 50ml/min~100ml/min; The minimum stable flow rate of the high pressure flow valve is 2.5ml/min~20ml/min.

  3. Selection of relief valve

    Direct-acting relief valve has fast response, suitable for brake valve and small flow safety valve, pilot operated relief valve has good opening and closing characteristics, suitable for pressure regulating valve, back pressure valve and large flow safety valve. The minimum setting pressure of the pilot operated relief valve can generally only be in the range of 0.5~1Mpa. When selecting the relief valve, it should be selected according to the maximum flow of the hydraulic pump, and attention should be paid to the minimum stable flow allowed by it, generally speaking, its minimum stable flow should be more than 15% of the nominal flow.

  4. Selection of check valve and hydraulic control check valve

    When choosing a check valve, you should pay attention to its opening pressure, the opening pressure is small as a check valve, and the opening pressure is large as a back pressure valve. Hydraulic control check valve has internal leakage type and leakage type, the leakage type has a lower control pressure and reliable work, but there is an additional oil drain pipe.

  5. Selection of directional valve

    According to the flow rate to choose the structural type, the general flow rate is above 190L/min, it is advisable to choose a two-way cartridge valve, below 70L/min can choose a solenoid directional valve, otherwise an electro-hydraulic directional valve is required. According to the commutation performance and other selection of electromagnet type, because DC electromagnets, especially DC wet electromagnets have a long life and high reliability, so DC wet electromagnetic directional valves should be selected as much as possible. Select the function of the spool valve according to the system requirements, for the system with particularly high reliability requirements, the rated pressure of the valve components should be much higher than its working pressure.


Any component in the hydraulic system may affect the normal operation of the whole system, there are many hydraulic parts on the market, but not all hydraulic components are high quality, excellent hydraulic components must have a reliable hydraulic parts supplier, which has to introduce you to elephant fluid power, we are a collection of manufacturing and distribution as one of the hydraulic components manufacturers, our technical team has many years of industry experience, can provide you with hydraulic system professional solutions, Quality assurance is many times better than similar products on the market, many orders are sent all over the world every day, we also provide warranty service, during the warranty period, our professional team will serve you throughout the process.
