1.Excellent corrosion resistance: High-quality corrosion-resistant materials are used to manufacture the diaphragm and the valve body. For example, corrosion-resistant rubber, polytetrafluoroethylene, etc. are used as the materials for the diaphragm, and cast iron, cast steel, stainless steel, etc.
In the complex environment of industrial production, safety is always the top priority. The 300LB forged long-stem gate valves made in China by J-VALVES are a solid shield safeguarding industrial safety, leaving you free from worries.
In the industrial field, J-VALVES red flange gate valves have become an ideal choice in numerous scenarios with their unique charm. Inside industrial plants, the pipelines in industries such as chemical and petroleum are crisscrossed, just like a complex network. The red flange gate valves stand out conspicuously in this "steel jungle". When workers conduct inspections and operations, they can quickly locate these valves due to their eye-catching red color and efficiently control the cut-off or conduction of fluids, ensuring that the production process proceeds in an orderly manner. The professionalism they convey also meets the strict requirements of high-quality valves in industrial production.
In the world of valves, the 1" 2500LB globe valves made in China by J-VALVES possess unique charm and are worthy of your preference.
In terms of surface pretreatment before painting A high-quality paint process first requires strict and meticulous treatment of the valve surface. In this process, oil stains, rust, and other impurities on the valve surface need to be removed. For example, through mechanical grinding, chemical degreasing and derusting, etc., the valve surface can be made flat, clean, and have an appropriate roughness. This treatment lays a good foundation for the subsequent painting and ensures that the paint layer can firmly adhere to the valve surface. If the surface treatment is not in place, the paint layer is prone to peeling and flaking, which will affect the overall quality of the valve. And a rigorous paint process can ensure that the surface treatment meets high standards every time, thus guaranteeing the stability of the subsequent paint layer.
