Characteristics
The stainless steel gate valves can operate stably within the range of -200 ℃ (ultra-low temperature liquid nitrogen working condition) to 600 ℃ (high temperature steam working condition), and are not easily oxidized or deformed at high temperatures, with no risk of brittle fracture at low temperatures. It has a wider temperature range and is suitable for more extreme working conditions.

Advantages
1. Flexible structural adaptability
It can be designed as a visible or hidden stem structure, with the visible stem type valve stem exposed, which can intuitively determine the opening and closing status, and the valve stem is not easily corroded by the medium; The concealed rod structure is compact and suitable for scenes with limited space. Meanwhile, stainless steel material has strong processability and supports various connection methods such as flanges, butt welding, clamps, etc., adapting to different pipeline installation requirements.
2. Lightweight and environmentally friendly
The strength of stainless steel is higher than that of carbon steel. Under the same pressure level, the wall thickness of the valve body of stainless steel gate valve can be appropriately reduced, and the overall weight is 10% -20% lighter than that of carbon steel gate valve, reducing the load-bearing pressure of pipeline installation. In addition, stainless steel material can be 100% recycled and reused, which meets environmental requirements and poses no risk of waste pollution.

Packing
Standard export wooden case packaging

Application Scenarios
The stainless steel gate sluice valves widely used in chemical industrial park, pharmaceutical pure water, seawater desalination system pipeline.
