The Ministry of Commerce released preliminary mid-term review of dimethylcyclosiloxane

On January 16, 2006, the Ministry of Commerce of the People's Republic of China announced the imposition of anti-dumping measures on imports of primary dimethylcyclosiloxane from Japan, the United States, the United Kingdom, and Germany. These measures took effect on the same date. The decision was aimed at protecting domestic industries from unfair competition caused by dumped products. In February 2007, Dow Corning Corporation of the United Kingdom submitted a request for a mid-term review of the existing anti-dumping duties imposed on its products. The application included initial evidence suggesting that the dumping margin had decreased significantly. After reviewing the submitted information, the Ministry of Commerce issued a public notice on April 25, 2007, confirming its decision to conduct a formal review of the anti-dumping measures applied to Dow Corning UK. The scope of the review focused on the company’s normal value, export price, and the calculated dumping margin. The product under investigation remained the same as in the original case: primary dimethylcyclosiloxane, which is classified under tariff code 38249090 in the Chinese Import and Export Tariff. Following the investigation, the Ministry of Commerce determined that the dumping margin for Dow Corning Limited was 5.4%. Based on this finding, the Customs Tariff Commission of the State Council decided to adjust the anti-dumping duty rate for imports of the product from Dow Corning UK Ltd., effective from April 25, 2008. Under the revised regulations, importers must pay anti-dumping duties when importing primary dimethylcyclosiloxane from Dow Corning Co., Ltd. The calculation is based on the ad valorem customs value of the goods. The formula used is: anti-dumping tax amount = customs duty-paid price × anti-dumping tax rate. Additionally, value-added tax will be calculated using the total of the duty-paid price, import duties, and anti-dumping duties as the taxable base. Interested parties have the right to apply for administrative reconsideration or file an administrative lawsuit according to the provisions of Article 53 of the Anti-Dumping Regulations of the People's Republic of China. This announcement came into effect on April 25, 2008, marking a significant adjustment in the trade policy regarding the imported chemical product.

Y Type Control Basic Valve

The Y-type basic valve of Aone-Best is the basic mother valve of all hydraulic control valves. It can equiped with different pilot to adapt to different occasions from the function. For example, with a pressure reducing pilot, the whole valve is a pressure reducing valve; with a pressure relief pilot, the whole valve becomes a pressure relief valve, and so on. Valves are available in a variety of size and flange standards for selection, widely used in municipal water supply, building water supply, air conditioning, fire protection, industrial water, power and irrigation facilities.

When the fluid flows through the valve at a higher flow rate, the pressure drops down. When the pressure drops to the saturation pressure of the liquid, the liquid will vaporize and form bubbles in the fluid. When these bubbles pass through the valve at high speed, they will cut the internal parts of the valve, and the destructive force of bubbles is equal to the damage of sediment and other impurities on the valve. At the same time, cavitation phenomenon can also bring obvious noise and vibration.

When a basic valve is used as a pressure reducing valve or a pressure relief valve, the cavitation phenomenon may occur due to the large differential pressure between the inlet and outlet of the valve.
