Some customers say why the price of Dongfeng electric ball valve is higher than that of some products on the market. First, our products are of fine workmanship. Second, the composition materials are different from those on the market. What are the composition materials of the electric ball valve? Now let's introduce: pipe body: in order to have a longer service life, it is all made of stainless steel 304 normal material, and supports various spectrometers to detect. The thickness is all thicker than the industry standards.
Connecting flange: all flanges are made of authentic forged materials from Shanxi, which are superior in strength and sealing. Do not compare the cast steel and steel plate flanges on the market. There is no comparability.
Welding materials: all welding materials shall be higher than the grade standard of the base metal, so as to make the welding points more secure. Limit padeye: all padeyes are produced with enlarged and thickened size, which is superior to the same model in the same industry. Limit screw: all screws are Grade 8.8 high-strength galvanized to ensure the comprehensive strength of the product. It is meaningless not to compare with Grade 4.8 in the market.
