The steam bellows globe valve is specifically designed for high-temperature and high-pressure steam systems. It adopts an all-metal bellows sealing structure, effectively preventing medium leakage.
○ Nominal diameter: DN15-DN400
○ Nominal pressure: PN16-PN64bar
○ Applicable medium: saturated steam, superheated steam, high-temperature condensate water
○ Operating temperature: Standard type ≤ 450°C; High-temperature type ≥ 540°C
○ Connection method: flange
○ Valve body material: WCB, 304, 316L
○ Bellows material: stainless steel, alloy steel, special steel
○ Sealing form: dual sealing with metal bellows and graphite packing (zero external leakage)
○ Operating mode: handwheel, pneumatic, electric
○ Flow direction requirement: low inlet, high outlet
○ Design standards: API 602, ASME B16.34, BS 5352
○ Test standards: Shell test at 1.5×PN, seal test at 1.1×PN (as per API 598)
○ The bellows sealing structure is adopted to completely prevent the leakage of steam medium.
○ Excellent high temperature resistance, suitable for saturated and superheated steam conditions.
○ The operating torque is small, making the operation convenient, and it remains sensitive and reliable even after long-term use.
○ The valve body material has high strength and strong resistance to thermal fatigue and thermal shock.
○ With a long service life and minimal maintenance, the corrugated pipe can withstand tens of thousands of cycles.
○ Control of main steam pipeline and auxiliary steam system in thermal power plants.
○ Steam heating, distillation, and reactor steam supply pipelines in chemical plants.
○ Clean steam sterilization and process heating system for the food and pharmaceutical industry.
○ High-temperature and high-pressure steam transmission and distribution pipeline network in the paper printing and dyeing industry.
○ Steam main pipeline and user-end metering and regulating devices for district heating stations.
