Typical Applications:

For most mediums which contains solid particles, abrasion is a very troublesome problem for valves and pipe fittings. Butterfly valve is one of the most common valve types in pipelines. If  working medium is abrasive, service life of both soft sealing and metal sealing butterfly valves is very short. To solve this problem, Foyo developes Lug type ceramic butterfly valves to meet the requirements of high abrasive applications. If working medium is both abrasive and corrosive, we can select suitable body materials for lug ceramic butterfly valves to avoid possible corrosion.

Design Features:
Product type
1.Lug type ceramic butterfly valves are light and easy to install.

2. FOYO triple eccentric design ceramic butterfly valves have low friction and excellent tightness in abrasive mediums. Meanwhile operation torque of  lug type ceramic butterfly valves is much lower than common metal seated butterfly valves.

3. Ceramics-to-Ceramics seated 
The disc sealing ring and seat are both high performance ceramics. High pure 99% Al2O3, Zirconia, Si3N4, and solid Tungsten carbide T.C. are used for Foyo lug type ceramic butterfly valves. Different ceramics materials are suitable for different applications. Foyo’s experienced engineers can help customers to select suitable materials for their specific applications.
4. Extended service life of ceramic butterfly valves can minimize maintenance cost for customers
Because of high hardness and excellent corrosion resistance of high performance ceramics, Foyo ceramic butterfly valves have much longer service life than any other common butterfly valves, and save maintenance cost for customers.

Temperature range of Lug Type Ceramic Butterfly Valves
-29℃~180℃ (normal)
-29℃~300℃（High Temperature）

Valve tightness 
Leakage rate of Foyo Lug type ceramic butterfly valves is Class VI for DN100 (4inch) and smaller sizes, Class V for DN125 (5inch) and larger sizes.
