Hydraulic control valve (referred to as hydraulic valve) in the hydraulic system function is to control the flow of oil in the hydraulic system, pressure and flow, so that the actuator and its driving mechanism to obtain the required direction of motion, thrust (torque) and speed of motion (speed). Any hydraulic system, no matter how simple, can not lack hydraulic valve; Hydraulic mechanical equipment with the same process purpose can be used in different combinations of hydraulic valves to form a variety of hydraulic system schemes with completely different oil path structures. Therefore, the hydraulic valve is the most varieties and specifications of hydraulic technology, the most widely used, the most active part (components); A new design or running hydraulic system, whether in accordance with the established requirements of the normal and reliable operation, in a large extent depends on the performance of the various hydraulic valves used and parameter matching is reasonable.

The large amount of pollutants emitted by heavy-duty vehicles is one of the important factors that pollute the environment. In 1999, the national environmental protection agency set emission standards for the exhaust gas analysis phase (total of four stages) of China's motor vehicles in accordance with the EU's emission standards for cars, which stipulates that starting from July 1, 2008, Phase III emission standards should be implemented The emission of pollutants from Taiwan's engines will be reduced by more than 30% from the previous period. This requirement will have a great impact on the transportation industry and automobile manufacturing industry.
In order to meet this demand, China National Heavy Duty Truck (SCTN) continues to accelerate the pace of independent innovation while continuously making progress in the world's production of heavy trucks. In 2007, it completed a full range of autonomous products with electronically controlled EGR and high-pressure common rail country III emissions. The core technology has broken the monopoly barriers of foreign enterprises' technology, and the performance advantages such as product price, use cost and oil adaptability have been fully affirmed by users.
In order to meet Datong’s need to continuously increase environmental pollution control and the country’s implementation of Phase III emission standards, Beiyue Construction Machinery Development Co., Ltd. took the lead in introducing new products of the III standard series to meet customers in the Datong area to cope with the “National III era†belt. The challenge.
On the morning of the 5th, the leading geese of CNHTC, a Chinese heavy-duty vehicle manufacturer, which was introduced by Beiyue Construction Machinery Development Co., Ltd., landed in Datong, China, and will produce severe pollutant emissions from heavy-duty trucks in Datong City for a long time. positive influence.
