Curtis Tube Fittings, Manila, Philippines, is a well-known producer and supplier of high-quality tube fittings and valves. With emphasis on precision and durability, Curtis supplies industries that need dependable solutions for fluid and gas systems. One of their top products, the Stainless Steel 321 Ball Valve, is used for high-temperature applications. It provides superior resistance to corrosion and oxidation, with long-lasting, leak-tight performance in severe conditions, especially in thermal and industrial applications.
The Stainless Steel 321 Ball Valve is constructed using austenitic stainless steel alloy containing titanium, which stabilizes the alloy and avoids carbide precipitation in high-temperature conditions. The alloy provides superior resistance to corrosion and oxidation, particularly in high temperatures. The tensile strength of ball valve is high, and it has good durability along with stress corrosion cracking resistance. The physical properties of ball valve are that it has outstanding thermal fatigue resistance, good toughness, and the capability to withstand both high and low temperatures with ease, which provides long-term reliability.
