Cast Steel Gate Valve

Cast steel gate valves can only be fully opened and fully closed to be used for cutting in the pipeline.The entire flow channel is a straight-through passage when the valve is fully-open, and the pressure loss of medium running is minimum.Gate valve is usually for working condition in which the valve is not opened or closed frequently, It's not suitable for adjustment or throttling.The most important feature of the cast steel gate valve of TANA machine is that they can be ensured that the permissible leakage rate can be lower than that specified in API 6D and API 600, and the middle shaft sealing can pass the USA VOC leakage test. Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel may be selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea.
