Applications typiques

For metal seated globe valves, the metal seat and disc sealing face is easily to get damaged if medium is corrosive or abrasive. Bolted Bonnet Ceramic globe valves were developed by FUVALVE to solve these corrosion and abrasion problems. Bolted Bonnet Ceramic globe valves are widely used in many severe applications, such as sea water, corrosive slurry, ect.

Caractéristiques de conception:

Type de produit

Bolted bonnet ceramic globe valves have many body structures for customers as below:

Straight pattern, angle pattern, Y pattern, forged body. These structures are all available for FUVALVE bolted bonnet ceramic globe valves. Rising Stem with precision threads and suitable for horizontal installation. Variable ceramic trim, including ZrO2 ceramics, type de chapeau pour les basses pressions nominales et chapeau à joint de pression, nitrure de silicium, tungsten carbide ,which make sure that ceramic globe valves have excellent abrasion resistance and corrosion resistance. Spherical seat face and conical ceramic disc ensure that ceramic globe valves are zero leakage. One piece body and bonnet.

Écart de température

Depends on the material used for bolted bonnet ceramic globe valves, the normal working temperature is -29~250 degree.

Etanchéité des soupapes

The disc and seat sealing face are well polished so that all bolted bonnet ceramic globe valves have tight shut off properties. The leakage class is up to Class VI.
