Globe Valve

Widely used in fields such as petroleum, chemical engineering, metallurgy, construction engineering, water supply, etc

1. The product is designed and manufactured according to the national standard GB2235, with a reasonable and reliable structure, excellent performance, and beautiful appearance. 2. The sealing surfaces of the valve disc and valve seat are made of iron based alloy or Stellite cobalt based hard alloy by surfacing welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, scratch resistant, and has a long service life. 3. The valve stem has undergone tempering and surface nitriding treatment, providing good corrosion resistance and scratch resistance. 4. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements. 5. The valve body material variety is complete, and fillers and gaskets can be reasonably selected according to actual working conditions or user requirements, suitable for various pressure, temperature, and medium working conditions. 6. The inverted seal is made of strontium pattern connection seal seat or stainless steel body welding, which is reliable in sealing. Filler replacement can be carried out conveniently and quickly without affecting system operation without stopping the machine.
