Ceramic-lined Butterfly Valve

1.The material of the moving parts is structural ceramics.Eccentric structure is used to reduce the friction of the moving parts and prolong the life of the valves.

2.The materials of the ceramic seal rings,O-rings,disc and pivots can be replaced if necessary.

The ceramic butterfly valve can be applicable to the environment of high wear,high temperature,and high corrosion.

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, Fuvalve 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.


  1. FUVALVE 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 Fuvalve lug type ceramic butterfly valves. Different ceramics materials are suitable for different applications. Fuvalve’s experienced engineers can help customers to select suitable materials for their specific applications.


  1. 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, Fuvalve 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)
