This page explains how Globe Valve is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A linear motion valve that regulates flow by moving a disc against or away from a seat, providing precise throttling and tight shut-off.

Globe valves are commonly available in pressure ratings of PN 16 to PN 40 bar per ISO 7005, or Class 150 to Class 300 lb per ASME B16.34. The actual rating depends on the valve size, body material, and design. Always confirm the specific rating with the manufacturer for your application.
Body materials include WCB (cast carbon steel), CF8 (cast stainless steel 304), CF8M (cast stainless steel 316), brass, and cast iron. Trim materials include PTFE for seats and Stellite for disc and seat overlays to provide wear resistance. The choice depends on the service conditions and compatibility with the fluid.
Tight shut-off is achieved when the disc is moved linearly to fully contact the seat, creating a metal-to-metal or soft seal. For soft-seated valves, the PTFE seat can meet Class VI leakage per ANSI/FCI 70-2, with a maximum allowable leakage of 0.01 ml/min. The sealing performance should be verified with the manufacturer.
Relevant standards include ASME B16.34 for pressure-temperature ratings, API 623 for steel globe valves, ISO 15761 for steel gate, globe, and check valves, GB/T 12235 for Chinese standards, and EN 13789 for European standards. These standards provide design, testing, and dimensional requirements. Always verify compliance with the manufacturer.
