Robinet à tournant sphérique pneumatique en céramique avec raccord à bride à joint dur Q641TC, wear-resistant valve product description
Q641TC pneumatic ceramic ball valve has outstanding characteristics such as superior corrosion resistance, high temperature resistance, wear resistance and erosion resistance. It is widely used in various acid-base salt gas, liquid, high-temperature steam and mud transportation systems in petrochemical, métallurgie, fabrication du papier, power stations, oil refining and other industries. It is an ideal substitute for titanium metal valves and Monel valves in highly corrosive situations. Zirconia ceramic ball valves have the advantages of low cost, high operating economy and long life (2 à 4 times that of titanium valves). Its driving modes include manual, pneumatique, pneumatic-spring return, électrique, etc.. And various types of special ceramic valves can be designed according to user requirements. It is suitable for various acid, alkali, salt liquid and gas medium environments. The hard-sealed valve is especially suitable for particles and fibrous medium environments.
Robinet à tournant sphérique pneumatique en céramique avec raccord à bride à joint dur Q641TC, wear-resistant valve Product features
The valve ball, valve seat and internal parts of the valve body that are in contact with the medium are all structural ceramic materials, which have excellent corrosion resistance, wear resistance and erosion resistance.
The valve ball and valve seat are precision ground to achieve zero leakage.
