Home > Stainless Steel Ball Valves
Midland, UK-based Weston Stainless is a reputable exporter of premium quality stainless steel items, including Stainless Steel Valves. These are offered in types like 304, 316, 321, and 904L to provide high resistance to corrosion as well as hardness. They can be provided in different forms such as ball, gate, globe, check, and butterfly valves for smooth flow control. Made of austenitic, ferritic, and duplex stainless steel, they possess superior mechanical strength and heat resistance. They meet international standards and are extensively used in precision, reliability, and long-lasting flow regulation systems in industries.
Stainless Steel Valves consist of components such as chromium (16-25%), nickel (8-20%), molybdenum (0-4%), and traces of carbon, manganese, silicon, and phosphorus, which make them more resistant to corrosion and wear. Mechanically, these valves have tensile strength of 515-750 MPa, yield strength of 205-550 MPa, and elongation of 30-40%. Their physical properties are a density of about 7.9 g/cm³, thermal conductivity of 14-16 W/m·K, and oxidation resistance up to 870°C, which provides efficient operation in high-pressure and extreme temperature conditions.
