Zirconia Ceramic Valve Plunger | Custom ZrO2 Valve Core with Cross Holes for Fluid Control

Zirconia ceramic valve plungers and valve cores machined with cross-drilled ports, sealing grooves and stepped bores. Zirconia will not corrode in the fluids that destroy stainless steel and keeps its sealing geometry for the whole service life.
