Globe Valves
What are Globe Valves?
Globe Valves are linear motion valves designed primarily for regulating flow in pipelines. Unlike gate valves, they feature a disk that moves perpendicular to the seat, enabling precise throttling and tight shut-off. These valves are ideal where flow control and frequent operation are required—especially in steam lines, cooling systems, and chemical plants.
Asiad Steel Industries is a reputed manufacturer and supplier of premium-grade Globe Valves under the Racer brand, built to meet demanding industrial applications across diverse sectors.
