Pressure Seal Bonnet Gate Valve：
The gate valve can only be fully opened and fully closed to be used for cutting in the pipeline. It has such features as unlimited installation direction, small disturbed current, low pressure drop, shorter face-to-face dimension, good sealing performance and wide application range. The most important feature of the steel gate valve of TSV Group is that it can be ensured that the permissible leakage rate can be lower than that specified in API6D and API600, and the middle shaft sealing can pass the USA VOC leakage test. TSV Group can provide trims of various materials including materials specified by API600. We can also provide valves of various casting materials, such as carbon steel, stainless steel, alloy, Hastelloy, nickel chrome and etc.
