Product Description
Forged steel internal thread, the sealing surface of the socket check valve is made of iron-based alloy or Stellite cobalt-based cemented carbide surfacing surface for wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, long service life, etc. Features. The connection between the stainless steel pin shaft and the valve disc adopts the built-in structure, which has excellent performance and more reliable sealing. The products are widely used in the pipelines of petroleum, chemical, pharmaceutical, electric power industries and other working conditions to prevent medium backflow. Applicable media are water, oil, steam, gas and some corrosive liquid media.
