Bellows Sealed Globe Valve is a linear-motion valve designed for reliable flow isolation and regulation in industrial piping systems where minimizing stem leakage and fugitive emissions is important. Unlike a conventional packed globe valve, the valve uses a metal bellows assembly as the primary stem sealing barrier, separating the process fluid from the external atmosphere. The valve combines the throttling capability of a globe valve with a bellows-based stem sealing arrangement. It is commonly considered for applications involving steam, thermal oil, hazardous chemicals, toxic fluids, hydrocarbons and other process media where conventional packing leakage needs to be minimized.

Frequently Ask Questions

Valve size is selected based on flow rate, pressure drop, media properties and required flow capacity (Cv).
A Globe Valve is generally more suitable for throttling because of its flow-control design.
Yes. Electric actuators can provide remote or automated operation when correctly sized.
Commonly referenced standards include ASME B16.34, EN 13709, BS 1873, API 598 and ISO 5208, depending on the valve and project requirements.
ASME B16.34 specifies requirements related to valve design, pressure-temperature ratings, materials, dimensions and testing.
BS 1873 is a British Standard for steel globe and globe stop/check valves, commonly used in petroleum, petrochemical and related industries.
Globe valves can provide throttling and isolation, while gate valves are primarily designed for full-open or full-closed isolation.
Yes. Pneumatic actuators can be selected based on required thrust, stroke and operating conditions.
Proper sizing, suitable trim, controlled pressure drop and anti-cavitation designs can help reduce cavitation.
ISO 5208 defines pressure-testing procedures and leakage-rate criteria for metallic industrial valves.
API 598 specifies inspection and pressure-testing requirements for applicable industrial valves, including shell and closure tests.
