The product is designed and manufactured according to the national standard GB/T 12236, with a reasonable structure, reliable sealing, and excellent performance. The sealing surfaces of the valve disc and seat are made of iron-based alloy or Stellite cobalt based hard alloy by welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, has good scratch resistance, and has a long service life. Various piping flange standards and flange sealing surface types can be adopted to meet various engineering needs and user requirements.

The valve body material variety is complete, and the gasket can be reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.

. The valve disc rotates around the pin outside the valve seat to reduce the violent impact during closure. The connection between the pin shaft and the valve disc adopts an internal structure, which eliminates any external leakage points and is more reliable to use.
