Product Overview

Core Material & Performance Advantages

• Q235B Body Material: Adopting national standard high-quality Q235B carbon structural steel, it has excellent welding performance, mechanical strength and impact toughness, perfectly adapting to the working conditions of medium-temperature, dust-containing media such as blast furnace gas and flue gas. It has strong corrosion resistance and deformation resistance, and its service life is far longer than that of ordinary carbon steel valves.
• High-Pressure Sealing Design: Equipped with double sealing structure and high-precision processing technology, the sealing surface of the valve plate and valve seat fits tightly, which can withstand PN15/25 high-pressure working conditions. The zero-leakage shut-off performance meets the safety requirements of high-risk medium transmission, effectively preventing potential safety hazards caused by gas leakage.
• Manual Worm Gear Actuator: Configured with heavy-duty worm gear transmission mechanism and handwheel operation device, it is labor-saving to operate, stable to open and close, and can accurately control the valve switch state. No additional power source is required, adapting to on-site working conditions without power supply, with convenient maintenance and high reliability.

Applicable Conditions & Application Scenarios

• Applicable Media: Blast furnace gas, flue gas, dust-containing gas and other high-risk media in the metallurgical industry
• Applicable Pressure: PN15, PN25 (1.5MPa, 2.5MPa)
• Applicable Diameter: DN100, DN200
• Core Applications: Blast furnace gas pipelines in steel plants, metallurgical flue gas emission systems, gas recovery pipelines, coking plant gas transmission and other working conditions requiring high-pressure shut-off and safety isolation

Product Structure Features

1. Inserted Blind Plate Structure: The valve plate can be completely pulled out to realize physical isolation of the pipeline, meeting zero-risk operation requirements during maintenance
2. Detachable Access Door Design: The side access door with sealing gasket allows inspection and maintenance of internal seals and valve plates without disassembling the entire valve, greatly reducing operation and maintenance costs
3. Anti-Jamming Guide Structure: Built-in high-precision guide groove and anti-jamming design, avoiding valve plate jamming caused by dust-containing media, ensuring smooth opening and closing
4. Fully Welded Body Process: The valve body is formed by integral welding, with high structural strength and no leakage risk, adapting to long-term stable operation under high-pressure working conditions
