Through Conduit Slab Gate Valve - E50B
This type is designed and produced for pipelines. It should be preferred for On-Off services. Emergency Shutdown, Line Break and Remote Control types provide sound operation of the line. They are manufactured with a full bore section equals to pipeline cross section. Opening without decreasing the differential pressure is not recommended.
These Gate Valves are designed as pipeline valves and have piggable feature. Disc is designed as one-piece slab and the rings are floating type.
