Globe Valves

Industry Definition & Scope
The globe valves industry encompasses the design, manufacturing, and application of linear-motion valves characterized by a spherical body shape and a movable plug (disc) that seats against a stationary ring to regulate fluid flow. Renowned for precise throttling capabilities, excellent shutoff performance, and versatility in pressure and temperature ranges, globe valves are essential components in industries requiring accurate flow control and regulation.
