○ 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.
The bellows globe valve for natural gas utilizes a metal bellows sealing structure to prevent external leakage, making it suitable for gas pipeline systems.
The Y-shaped bellows globe valve adopts a straight-through and direct-flow structure. This structure features low fluid resistance
The high-temperature steam bellows globe valve utilizes a fully metal bellows seal, capable of withstanding temperatures up to 600℃, with zero external leakage.
