The stainless steel valves are considered to be prominent in a wide variety of industries and applications because of operational characteristics such as high strength, resistance to corrosion, and capacity to operate at high temperatures and pressures. These reduce the valve ability to work under harsh environmental conditions; these valves are made from steel that has been alloyed with chromium. Some of the common applications where such machines are employed include chemical processes, medical products, gas and oil, food/ beverages and many others. These characteristics, including high rust and scaling resistance, allow the product to maintain a long duration of dependable supplementation to fluids. Stainless steel valves are available in a broad range that consists of ball valves, gate valves, and butterfly valves and provide improved efficiency in the use of equipment in industries. We have wall thickness in mm: 0.5, 0.6, 0.7, 0.8, 1, 1.2, 1.6, 2, 2.6, 3, 3.2, and 3.6. We understand that every industry has unique requirements when it comes to valve applications. That's why we offer a wide range of options for our customers to choose from, including ball valves, control valves, fire hydraulic valve gate valves, syphon tube valves, strainer valves, and globe valves, all available in different sizes and pressure ratings with the following specifications: Outer Diameter (MM): 6.35, 7.93, 9.52, 12.70, 15.87, 19.05, 22.22, 25.40, 31.750, 38.10, 44.45, 50.80, 63.50, 76.20, 88.90, 101.60, 127.00, 139.70, 152.40, 165.10 Outer Diameter (inches): 1/4",, 5/16”, 3/8”, 1/2", 5/8”, 3/4”, 7/8”, 1”, 1¼”, 1½”, 1¾",, 2", 2½”, 3”, 3½”, 4”, 5”, 5½”, 6”, 6½” Whether you need a compact solution or a heavy-duty valve for extreme pressures and temperatures, we have got you covered with our diverse line of corrosion-resistant stainless steel valves.
