Gate Valves – Through Conduit

A valve world-renowned for excellent design, high quality and reliability. The C-G4 Through Conduit Gate Valves are available in a range of sizes and pressure ratings. The unique fabricated body of the C-G4 Through Conduit Gate Valve offers maximum strength whilst reducing the overall size and weight. This results in a much lighter, compact designed pipeline gate valve.
