Ceramic Partial Lined Butterfly Valve Sunyeh

Double eccentric structure with eccentric shaft and eccentric butterfly disc design. Because of the wedge effect produced by the eccentric core, the more closed, the tighter. And the contact between sealing rings can be compensated by themselves. lt has the properties of erosion resistance, corrosion resistance, high-temperature resistance, and crushing resistance.

The installation is convenient because of the design of clamp type and lightweight. And its actuator connection is through the bracket interface, which meets the lSO 5211 size standard.

All specifications of the stems are integral, high strength, 17-4PH stainless steel material, and the material could be changed according to different working conditions.

Maintenance of valve seat is convenient. As long as the insert is removed, the sealing pair can be replaced and maintained, and there is no need to disassemble the whole valve.

Double eccentric structure, allowing maximum flow through and minimum wear. When the sealing pair is opening and closing, there is a shearing performance. Ceramics have self-cleaning and self-wetting properties which help to clean scales and adhesives on the sealing surface and maintain long-term tightness

Ceramic Ball and Ceramic Seal match perfectly and the best sealing effect is realized. It ensures V or above shutdown level and better regulation performance.

Our ceramics are thick and solid. A reasonable, highly engineered, and thermal insulation control valve design proves that by using solid, thick-walled ceramic components and a unique combination, the valve can survive in continuous service much longer than that of hardening and spraying nickel-based tungsten carbide and surfacing materials.
