Swing Check Valve
Swing check valve is suitable for nominal pressure 1.0MPa~6.3MPa ; Nominal diameter DN15~600mm, it is used to prevent backflow of medium. With different materials (WCB, cf8 (m), cf3 (m), 1gr5mo, 15crmo1v), it can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea. Mainly used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other pipelines.

1. The valve flow is streamlined and the resistance is small
2. The opening and closing part is controlled by the medium itself to prevent backflow.
3. The sealing pair is advanced and reasonable, and the sealing surfaces of the disc and valve seat are welded by iron-based alloy or silicon-Lee Tae-cobalt-based cemented carbide, which has the advantages of wear resistance, high temperature resistance, corrosion resistance, strong scratch resistance and long service life.
4. The products can be used for various pipeline flanges, standard flanges and flange sealing types to meet various engineering needs and user requirements.
