Stainless Steel High-Temperature Ball Valve

Our Stainless Steel High-Temperature Ball Valve is specially designed for high-temperature and high-pressure industrial scenarios, adopting high-grade stainless steel materials and advanced sealing technology to ensure stable operation under extreme temperature conditions. The valve realizes rapid on-off control through 90° rotation of the ball, with compact structure, flexible operation and reliable sealing, which can effectively control the flow of high-temperature media such as steam, heat-conducting oil and high-temperature gas, and provide safe and efficient fluid control solutions for your industrial production.

With strict quality control and compliance with international industry standards, the product has passed CE, ISO, API 607 and other certifications, and its performance indicators are at the leading level in the industry, which can meet the customized needs of different countries and regions

1.Super High Temperature Resistance : Adopt high-quality stainless steel materials such as 316L, 310S and 2520, with different temperature resistance levels to meet the needs of different working conditions. The conventional model can withstand -40℃~550℃, and the special coating model can reach up to 1200℃, which can maintain stable mechanical properties without embrittlement or softening even in long-term high-temperature operation.

2.Excellent Sealing Performance : Equipped with innovative sealing technology, including elastic metal sealing and all-metal hard sealing. The ball and valve seat are lapped to achieve 100% contact, ensuring absolute shut-off. The leakage rate is lower than 0.001% ANSI standard, which can effectively prevent medium leakage and avoid safety accidents caused by high-temperature medium leakage.

3.Strong Corrosion Resistance : The valve body and internal parts are made of high-grade stainless steel, which has excellent corrosion resistance to high-temperature steam, corrosive chemicals, sulfide and other media. 316L material has passed NACE MR0175 anti-sulfur certification, which can be used stably in harsh corrosive environments for a long time without rust or damage.

4.Durable & Low Maintenance : The valve body adopts precision casting technology, with compact structure and high structural strength. The valve stem is designed with blow-out proof, and the surface is treated by nitriding to enhance wear resistance. The modular design is convenient for disassembly and maintenance, and the maintenance cycle is extended by 50% compared with ordinary valves, reducing maintenance cost and downtime.

5.Multiple Safety Designs : Integrated with anti-static and fire-proof designs, the metal hard sealing structure forms an electrostatic channel through close contact between components, which can conduct static electricity without additional devices. The flexible graphite packing and metal wound gasket can maintain sealing for 30 minutes in case of fire, complying with API 607 fire safety standard, winning key time for emergency disposal.

6.Flexible Operation & Wide Compatibility : It supports multiple driving modes such as manual (handwheel/worm wheel), pneumatic and electric, and the pneumatic actuator has a response time of ≤0.05 seconds, supporting explosion-proof (ATEX) and DCS/PLC remote control. Multiple connection forms such as flange (ANSI/DIN), internal thread (NPT/BSPT) and butt welding (BW/SW) are available to adapt to different pipeline systems.

- Petrochemical Industry : Used in catalytic cracking units, ethylene cracking devices, hydrogenation reactors, etc., to control high-temperature oil and gas, high-temperature reaction media, and withstand instantaneous high temperatures above 900℃ in cracking gas pipelines.

- Power Industry : Applied in supercritical thermal power units, nuclear power plants, etc., to control high-temperature steam in main steam pipelines and coolant systems, with stable operation under 620℃ and 25MPa conditions for a long time, and energy saving of 15% compared with gate valves.

- Metallurgical Industry : Used in steelmaking converter flue gas purification systems, non-ferrous metal smelting equipment, etc., to control high-temperature furnace gas up to 1200℃, resist the erosion of molten metal particles, and the service life is 5 times that of ordinary valves.

- Building Materials Industry : Suitable for glass melting furnaces, ceramic kilns, etc., to control high-temperature materials up to 1500℃, with sanitary surface treatment (Ra≤0.4μm) to prevent material adhesion and ensure stable product quality.

- Other Industries : Also widely used in pharmaceutical, food, aerospace and other fields, such as high-temperature sterilization pipelines in pharmaceutical industry, high-temperature fluid control in aerospace fuel pipelines, etc., to meet the strict requirements of different industries.
