Globe Valve
1. Product Overview
Globe valves are linear motion valves designed for precise flow regulation and reliable shut-off in piping systems. Their spherical body shape and disc-to-seat design provide superior throttling capabilities compared to gate or ball valves.
Key Advantages
✔ Precise Flow Control - Excellent throttling characteristics
✔ Positive Shut-off - Bubble-tight sealing (Class VI)
✔ Easy Maintenance - Top-entry design for in-line repair
✔ Versatile - Suitable for liquids, gases, and steam
✔ High-Pressure Capable - Designs available up to ASME 4500#
