Alumina ceramic piston valve element valve accessories valve rod hydraulic spool valve
Alumina Ceramics has high toughness, flexural strength and wear resistance, excellent thermal insulation performance, thermal expansion coefficient close to metal and other advantages. It also has a long service life. Therefore, zirconia ceramics are widely used in the field of structural ceramics. That is why we make the piston valve accessories and hydraulic spool valve parts of zirconia ceramic material, pump industry is no exception.
