Valmax Cast Steel Gate Valve Introduction:
The cast steel gate valves can only be fully opened and fully closed to be used for cutting in the pipeline. The cast gate valves have 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 cast steel gate valve of Valmax Valve Co., Ltd. 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. Valmax Valve Company can provide trims of various materials including materials specified by API 600. We can also provide valves of various casting materials, such as carbon steel, stainless steel, alloy, Hastelloy, nickel chrome, etc.
