Through Conduit Gate Valve


Through-conduit gate valves are isolating valves designed for full closing of the working media flow. They can be used for temperatures up to 200°C. If the gate valves are used for regulating or throttling purposes, the manufacturer does not guarantee the tightness. The gate valves are full-bore piggable valves with a flow resistance coefficient equal to that of the piping. Therefore they are suitable especially for long-distance pipeline systems
