The 310S National Standard Flange Ball Valve is a specialized flow-control solution designed for high-temperature industrial applications. Engineered in strict accordance with Chinese national standards (GB/T 12237), this valve features a standardized flanged connection that ensures a secure and reliable fit within domestic pipeline systems. Because it utilizes a precision-machined spherical ball, it provides an efficient quarter-turn mechanism for controlling the flow of high-heat liquids and gases.
Exceptional 310S Heat Resistance
This valve is manufactured from 310S (06Cr25Ni20), a high-alloy austenitic stainless steel designed for oxidation resistance at elevated temperatures. Consequently, it maintains excellent structural integrity even when exposed to continuous service temperatures up to 1150°C. Furthermore, the high chromium and nickel content ensures the valve remains stable and resistant to scaling in thermal processing environments where standard grades would fail.
Key Features and Engineering Advantages
In order to provide long-term safety and performance in demanding infrastructure, our flanged ball valves include the following characteristics:
- GB Standard Compliance: Every valve is built to meet strict national specifications for dimensions and pressure ratings. Therefore, it is perfectly compatible with domestic flanged piping, ensuring easy maintenance and replacement.
- Full Bore Design: The internal flow path matches the pipe diameter exactly. Additionally, this configuration ensures minimal pressure loss and prevents the accumulation of media, which is critical for maintaining system efficiency.
- Leak-Tight Sealing: We utilize advanced soft or metal-seated designs to guarantee a reliable shut-off. Specifically, these seats are engineered to handle the thermal expansion associated with high-temperature service without leaking.
- Robust Construction: Because the 310S material is exceptionally tough, these valves offer a long service life in high-pressure and high-heat applications. Ultimately, the simple quarter-turn operation allows for rapid and safe flow control in complex industrial automation systems.
Wide Industrial Applications
Whether you are managing furnace exhaust systems, petrochemical refining, or thermal power generation, the 310S National Standard valve delivers the performance you need. Specifically, its ability to withstand extreme heat makes it a vital component for heat treatment equipment and boiler systems. Consequently, choosing our GB-compliant 310S valves ensures enhanced operational safety and durability for your high-temperature facility.
