API 6D Through Conduit Flat Gate Valve Through-conduit gate valves are isolation valves designed to stop the flow of fluids. They can handle temperatures up to 200°C. However, if these valves are used to control or throttle the flow, the manufacturer does not ensure they will be leak-proof. These gate valves are full-bore, piggable valves with a flow resistance coefficient equal to that of the piping, making them particularly suitable for long-distance pipeline systems.
