Kalpataru Piping Solutions has been a leading manufacturer and exporter of Duplex Steel S31803 / S32205 Instrumentation Ball Valves for the past 25 years. We closely monitor market trends to develop products that meet current demands, offering a wide range of products in various standards, grades, materials, sizes, and shapes.
Duplex Steel S31803 / S32205 Instrumentation Ball Valves are known for their high performance and are made from a widely used duplex stainless steel grade containing molybdenum, nitrogen, and nickel. These austenitic-ferritic steel valves provide exceptional resistance to corrosion and high strength. They excel in resisting localized corrosion, including pitting, crevice, and intergranular corrosion, and offer good high-temperature oxidation resistance. Additionally, they are resistant to chloride stress corrosion cracking.
These valves are well-suited for use in brackish water, marine environments, and closed-loop water systems due to their excellent resistance properties. Compared to other grades, Duplex Steel S31803 / S32205 valves are highly ductile and tough, making them ideal for high-stress situations where other materials might fail. They are solution-treated at temperatures between 1020-1100°C and rapidly cooled, which enhances their properties without hardening through thermal treatment but through cold work processes.
Our commitment to quality and innovation ensures that our Duplex Steel S31803 / S32205 Instrumentation Ball Valves meet the highest standards and perform reliably in demanding environments.

FAQs
What is a duplex valve?
Duplex Steel Valves are composed of duplex-grade steels, which exhibit high strength and superior corrosion resistance. These steels have a microstructure consisting of both austenitic and ferritic phases, making them suitable for a wide range of applications due to their robust metallurgical properties.
What are types of instrumentation valves?
Instrumentation Valves -Needle, Ball and Manifold Valves range includes Needle Valves, Ball Valves, Manifold Valves, Safety Valves, Gauge Valves, Block and Bleed Valves.
What instrument has 4 valves?
Instruments with a fourth valve, like tubas and euphoniums, use it to lower the pitch by a perfect fourth. This compensates for the sharpness in valve combinations 1-3 and 1-2-3, providing better intonation and versatility, especially in lower registers.
