Superior Ceramic Plug Valves for Demanding Applications

About NGK Ceramic Plug Valves

NGK Plug Valves are engineered to resist attack by abrasive and corrosive chemicals with a solid, cast chemical ceramic lining and plug. Unlike PTFE-lined plug valves, the NGK design provides superior durability with a 3/8" thick cast lining, offering maximum corrosion resistance and longer valve life in all heavy-duty applications.

Key Advantages

3/8" thick cast ceramic lining
Superior to PTFE-lined valves (1/8" lining)
Eliminates liner collapse in vacuum service
Shore hardness D105 (vs D50 for PTFE)
Brinell hardness 650 (vs 200 for Titanium)

Ceramic Plug Valves
