Product Description
Gear Operated Concentric Wafer Type Ceramic Sealing Butterfly Valve (GD371TC)
This valve is applicable as an on-off or pipelines with high-hardness grains or with both soft grains and corrosive media. Its nominal pressure is 1.6MPa, and applicable temperature below 200 Deg C.

All medium-contacting parts are made of structural ceramic, featuring extremely high chemical stability and hardness (Rockwell Hardness (HRC90), only next to diamond. Therefore, this valve has extremely strong resistance to abrasion, corrosion and erosion, good heat insulation and small thermal expansion. 

The ball body is made with advanced grinding equipment and process, with high-precision ball roundness and good surface quality, and after facing-up with the valve seat, a good sealability can be obtained by means of self-lubrication of Zr02 Ceramic.

Thanks to the ceramic's strong resistance to abrasion, this valve is durable and extremely reliable, with a long service life being 2-4 times of that of Ti alloy and Monel Valves.
