Tank bottom valve

DN : 4"/3"
Class : 150 Lbs
Grade : 1.4408

These are valves whose manufacture is done in series so as to better amortize the cost of the cast pattern. Cast construction helps optimize the shape of the valve while reducing material costs. The cost of manufacturing a cast valve is inferieur to that of welded construction. Lead-times on the other hand, may be long depending on the time of manufacture at the foundry. Radiographs are often needed to ensure there is no porsity within these elements.
