PERFORMANCE ADVANGATE

1. Strong corrosion resistance: H44F fluorine-lined check valve adopts fluoroplastic lining, which 

has excellent corrosion resistance and can resist corrosion from a variety of strong acids, strong 

alkalis and strong oxidants. 

2. Wide range of applications: The valve is suitable for a variety of media, including water, steam, oil, 

nitric acid, acetic acid, strong oxidizing media and urea, etc.

3. Reliable sealing: The valve disc and shaft of H44F4 fluorine-lined check valve are designed as one, 

and all fluorine-lined materials make opening and closing flexible and sealing reliable. Even in 

low-pressure areas, good sealing performance can be guaranteed.

4. Long service life: Due to the use of corrosion-resistant fluoroplastic materials, H44F4 fluorine-lined 

check valve has the characteristics of wear resistance and long service life.
