I.C. Globe Valve Screw End
Investment Cast Globe Valve with BSP/NPT threading. Class 150. Sizes 1/2" to 2". For throttling and flow control.
Key Applications
Frequently Asked Questions
What is the difference between a gate valve and a globe valve?
Gate valves provide minimal restriction when fully open (straight-through flow) and are used for isolation (on/off) service. Globe valves have a spherical body with a disc that moves perpendicular to the seat, creating a throttling capability that precisely controls flow rate. Globe valves are preferred for flow regulation applications but have higher pressure loss than gate valves.
