Pneumatic single seat regulating valve

Pneumatic single seat regulating valve

Brief description: The single-seat valve structure is adopted, and the "corrosion-resistant king" 

polytetraethylene material is embedded in the valve body cavity, ensuring that the parts in 

contact with the medium are all polytetraethylene material. It has the advantages of good 

corrosion resistance, small size, light weight, smooth movement, and reliability. It is widely 

used in various highly corrosive media situations (such as hydrochloric acid, nitrogen, sulfuric acid, etc.) 

in petroleum, chemical, metallurgy, pharmaceutical and other industries.


Diameter: DN15-DN300 Pressure: PN16-PN25 Temperature: -30-180 Material: carbon steel,
