First, the American standard bevel gear valve characteristics

1, the product design and manufacture in line with the US national standard ANSI B16.34, the American Petroleum Institute standards API6D and API600 requirements. 
 2, compact structure, small size, good rigidity, safe and reliable seal. 
 3, closing pieces (gate) with flexible structure, in the work can automatically compensate for abnormal load or temperature caused by the deformation of the valve. Therefore, the seal is reliable and does not create gate wedges. 
 4, diameter greater than or equal to NPS10 ", pressure level 150 pounds and diameter greater than or equal to NPS6", pressure level 600 ~ 2500 pounds of manual valves, the operating device is equipped with rolling bearings, opening and closing easily. 
 5, the main material, the inner parts of materials, packing, gaskets, fasteners, materials, according to user requirements or the actual working conditions and reasonable combination. 
 6, NPS ≤ 10 "gate valve, the valve seat for the exchange of female threaded valve seat can be any combination of material with the closing piece sealing surface material to meet the conditions required to extend the service life.
