DIN Bellows Globe Valve
Nominal Diameter: 1" ~ 12"
Nominal Pressure: PN 10 ~ PN 160
Mediums: Water, steam, oil, gas, chemicals
Temperature Range: ≤ 650°C
DIN Bellows Globe Valve
DIN Bellows Globe Valve is designed according to DIN standards and is widely used in industrial pipelines requiring zero external leakage and reliable sealing performance. The bellows seal structure effectively isolates the stem from the external environment, preventing medium leakage and ensuring operational safety. Compared with conventional gland-packed globe valves, bellows sealed valves offer longer service life, reduced maintenance requirements, and enhanced environmental protection.
The valve is suitable for controlling or shutting off various media, including steam, thermal oil, hot water, ammonia, toxic fluids, flammable fluids, and other hazardous process media. It is extensively applied in power plants, chemical processing, petrochemical industries, oil & gas facilities, district heating systems, and industrial utility services.
As an experienced valve manufacturer, we provide comprehensive OEM and ODM services to meet diverse project requirements.
