In order to facilitate the operation of the driver, the high-end wheel loader pilot valve to control the hydraulic control Loader Multi Way Valve, and the valve stem moves to accurately supply the hydraulic oil from the Hydraulic Gear Pump to the hydraulic cylinder, realizing the work of the loader arm and Loader Bucket.
Pilot valves are auxiliary valves used to operate control mechanisms in other valves or components. Pilot valve itself is often a small specification control valve, mostly for pressure control valve. And fixed liquid resistance to form a pilot control liquid bridge, according to the input signal to control the main valve or secondary valve or variable bar; Can accept a variety of input methods, such as manual, electric, hydraulic, pneumatic, mechanical CAM, electric ratio, etc. China pilot valve, Liugong pilot valve, Sdlg pilot valve, Sem pilot valve, we provide you can trust the pilot valve.

The Semiconductor Lighting Technology Evaluation Alliance, China Semiconductor Lighting, LED Industry and Application Alliance recently released four LED lighting industry safety requirements, performance requirements and non-directional self-ballasted LED lamp specification classification and performance requirements in Beijing. standard. According to the National Electric Light Source Quality Supervision and Inspection Center (Beijing), China's LED lighting industry has many problems such as large number of enterprises, small scale, and uneven product quality. Product exports often face obstacles such as different standards and certifications in the international market. The four standards issued this time will fill the gaps in the relevant product fields in China, standardize and guide the sustainable and healthy development of enterprises. LED is an abbreviation for LED. Compared with incandescent lamps and energy-saving lamps, LED lamps have the advantages of more energy saving, longer life and less pollution, and represent the development direction of future lighting products. China is a big country in the production of LED lighting, which has a global output of about 90%, and its products are widely sold to the international market. In recent years, many cities in China have applied LED lighting equipment to roads, schools, shopping malls, hotels and so on. The National Electric Light Source Quality Supervision and Inspection Center (Beijing) has submitted a proposal for the classification of LED lamp specifications to the Lighting Products Technical Committee of the International Electrotechnical Commission this year, which has been widely recognized by the members of the world. This will greatly enhance China's participation and initiative in the development of international LED standards, and play its due role in the formulation of international standards for related products.
