★、The valve has the exceedingly high wear-proof capability, corrosion resisting, enduring capability, good heat insulation, small thermal expansion. All parts that the medium is made of ceramics. Its chemical stability and hardness are exceedingly high ( Rockwell hardness HRC90 )
★、Good wear-proof capability of ceramics make the valve hard to wear thus ensured high reliability. The lifespan is 2-4 times of titanium alloy valve and Mengnaier valve.
★、The valve fits in granule medium of high hardness, or medium with erosive soft granule. It is also the only valve suitable for this type of medium.
