The metallurgy industry involves demanding process conditions across iron and steel production, non-ferrous metal processing, smelting and material handling. Valves are required to operate reliably under high temperatures, abrasive media, dust, solid particles and frequent process cycling.
High Temperature Service
Metallurgical processes such as smelting, heating and processing can involve extremely high temperatures, requiring suitable valve materials and reliable sealing systems.
Abrasive Media
Slag, ore, powders and solid particles can cause severe wear and erosion of valve bodies, trims and sealing surfaces.
Dust & Solid Particles
Dust and particulate matter can enter valve cavities and sealing areas, potentially causing blockage, wear and operational difficulties.
Severe Operating Conditions
Frequent cycling, thermal variation, vibration and harsh process environments can place additional mechanical demands on valves.
Material selection depends on the medium, temperature, particle characteristics, pressure and specific process conditions.
