This valve is a high-safety special valve designed for natural gas transmission systems, integrating three functions: direct installation in the ground, pressure relief and fully welded construction. The valve adopts a one-piece welded valve body design and can be directly buried underground without the need to build a well for the valve. It is also equipped with a pressure relief device that can safely discharge residual natural gas into the valve cavity when the valve is closed, ensuring operational safety during pipeline maintenance and emergency repairs.
