Bellows sealed pneumatic single seat regulating valve

Bellows sealed pneumatic single seat regulating valve is used in industrial process automation control systems. It can automatically turn on or off when receiving electrical control signals, achieving control over the on/off or flow regulation of fluids in pipelines. This series of solenoid valves can be widely used in production and research departments such as textiles, printing, chemicals, plastics, rubber, pharmaceuticals, food, building materials, machinery, electrical appliances, surface treatment, as well as in daily living facilities such as bathrooms, canteens, air conditioners, etc.

The upper valve cover adopts a corrugated pipe sealing structure, which can eliminate the possibility of process medium leaking outward from the clearance of the valve stem movement, which is one of the significant features of the corrugated pipe sealing valve. Due to the deformation of the bellows element itself and the aging resistance of the valve, this type of regulating valve overcomes the weaknesses of the packing aging and temperature difference sensitivity that usually exist in the packing seal valve. Secondly, the double sealing structure of corrugated tube and packing is adopted for better safety and reliability. Therefore, it has been widely used in automatic control systems for rare and special media such as highly toxic, highly corrosive, and radioactive substances. The valve core has a large guiding area and good vibration resistance. It is equipped with a multi spring thin film actuator, which has a compact structure and high output force.
