Gate Valve

China gate valve manufacturers, gate valve suppliers, gate valve factory. Vatac standard Steel Gate Valves are designed and manufactured to ensure leakage of less than 100 ppm (parts per million) of volatile organic compounds. Extensive base line laboratory testing (static and cycle testing) has been performed establishing critical design parameters necessary to achieve low emission sealing in the Vatac stem packing seal area and in the bonnet gasket sealing area, In-house testing procedure has been developed and is periodically performed to ensure that standard product design and manufacturing criteria consistently result in the Vatac Gate Valve meeting a maximum of 100 ppm VOC leakage prior to shipment.


Vatac O-Ring Seal Block and Bleed Gate Valves are recommended for hard to hold services such as butane, kerosene, gasoline, propane, diesel oils, fuel oils, jet fuels, steam, air, natural gas, toluene, hydrogen, helium, and oxygen. Manifold tank farms, LPG areas, and airport fueling facilities provide excellent opportunities for savings with the O-Ring Seal Gate Valves. For effective double block and bleed service, the line media should be free of foreign matter and solids in suspension.
