High-Pressure Blast Furnace Gas Valves, Bleeder Valves & Stove Spares
Blast furnace gas control systems require heavy-duty valve assemblies designed to isolate or regulate the flow of toxic, dusty, and flammable crude blast furnace gas. Due to high working temperatures and abrasive dust particles, these valves must be engineered for complete tightness, reliable seal separation, and quick mechanical actuation.
Excellors designs, manufactures, and supplies custom-engineered industrial valves, and specializes in the professional refurbishment and overhauling of large-scale plant isolation valves, including Hot Stove Valves, Bleeder Valves, Cold Blast Valves, Draft Valves, and Goggle Valves. We have gathered a wealth of engineering knowledge for Bleeder systems and Gas Cleaning Plant (GCP) & Sintering Gas Plant (SGP) spares. Our valves range in size from **400 mm to 4000 mm** with working pressure ranges from **500MMWC up to 2.5 bar**. For optimum safety, our valves can be designed in fully closed configurations.
Key Technical Specifications
- Upper Bank Valve Refurbishment: Complete overhaul, valve seat grinding, seal replacement, and pressure safety checks.
- Valve Size Range: Diameters from **400 mm to 4000 mm** to fit hot stove and gas ducting lines.
- Working Pressure Capacity: Operates reliably from **500MMWC up to 2.5 bar** pressure range.
- Optimum Safety: Can be custom fabricated in fully enclosed configurations to isolate toxic BF gas.
- Hydrostatic & Pressure Testing: Shop pressure testing using calibrated analog gauges to verify zero leakage.
- Crude BF Gas Isolation: Engineered for hazardous media with working pressures up to 0.2 MPa.
- Thermal Durability: Rated for operational temperatures up to 300°C with silicone/EPDM seals.
- Gas-Tight Mechanical Seal: Lever clamping mechanism preventing ambient gas leakage.
- Robust Structural Flanges: Thick multi-hole flanges for secure connection to gas ducts.
Design & Performance Advantages
By utilizing high-grade expansion bellows and a simplified manual or motorized clamping layout, our valves minimize maintenance intervals in high-dust gas routing. Every newly manufactured and refurbished valve undergoes hydrostatic and pneumatic pressure holding tests at our testing station, monitored via calibrated gauges, to certify zero leakage at operating pressures.
Industrial Valve Optimization & GCP Spares
Gas Cleaning Plants (GCP) and metallurgical pipelines operate under extreme pressures, dust loads, and thermal expansions. Regular shutoff valves fail to maintain tight closures in such dusty crude gas environments. Excellors provides custom valve optimization, upgrading valve seat profiles, calibrating hydraulic/pneumatic actuators, and supplying precision spares to increase reliability.
Our optimized slide gates, bleeder valves, and equalizing valves are tested in our workshop for stroke alignment, limit-switch feedback, and pressure retention, reducing torque demands and extending seal life cycles in dusty steel plant piping.
