The design and manufacture of strict API600,API602 standards. Reasonable structure, reliable sealing, excellent performance, beautiful shape, sealing surfacing and welding Co - base hard alloy, wear - resistant, corrosion - resistant, anti - abrasion performance. Long service life. The valve stem has good corrosion resistance and abrasion resistance. The Class900(nominal pressure > 15.0mpa) cavity adopts self-tightening sealing structure. The sealing performance increases with the pressure, which ensures the sealing performance. The valve is provided with reverse seal structure and reliable seal. The dimensions of parts, flanges and butt welds can be reasonably selected and matched according to the actual working conditions or user requirements to meet various engineering needs. American standard cast steel gate valves of the main parameters: diameter: DN15 - level of DN800 mm pressure: 1.6 Mpa ~ 32 Mpa (150 lb to 600 lb) connection: flange sealing form: hard seal USES: by the drive mode: drive mode: manual flow direction: one-way temperature range: - 29 ℃ - 425 ℃ the valve body material: cast steel
