Applicable temperature: -196 C degree to 600 C degree
Note: please take notice to choose different materials for different working conditions.
Application: Common type: water, steam, oil, liquid gas, natural gas etc.
Anti-sulphur type: gas oil etc which contains h2s, co composition.

The stem connection to the gate is a T-head design which is integral (without welding) with the stem.
Besides the general gate valves, our company also can make cryogenic gate valve, jacketed gate valve, bellow seal gate valve and extended stem gate valve for underground installation application.

Also we can make the different trim material according to API trim chart, likely monel, hastelloy C, inconel, alloy 20 and so on.
