南通市电站阀门有限公司

1. ,,,,, The precise forging work of all series body, the surface is smooth and clean, any defection of casts is excluded, spurn the quality hidden trouble threatening the sets of machine, the condition of high temperature and high pressure is allowed. 2. ,,,, Special materials are compounded to ensure the high rigidity as well as its difference in rigidity. The surface of disc and seat are critically burnished so that they are very abrading endurable and anticorrosive and looked like the mirror which prolonged the circle of use. 3. ,,, Take design of self-sealing, reduce the potential leak points to bottom, protect the packing effectively, avoiding any leakage. 4. ,,, High water pressure shell test, high gas pressure shell test and audit of damage which generally control the quality of valve. 5. ,,, The surface of the steam is precisely polished and hardened .It is farthest durable for bruise and corrosion. All of our strict test and inspection tools ensure the high quality and the torque reducing as well as the more convenient manipulation. 6. ,,,,,, We take the design of using special corrode delay packing in the valves structure which are high temperature and high pressure durable and can self-lubricate which can decrease the friction in the opening and closing process, besides that ,the unique design avoids the corruption of the surface of the stem so that the upper leakage is prevented. 7. , Quickly open and close, meet the rigorous demand of various special working conditions. 8. , 90% , Our strict manually burnishing assures the over 90 percents inosculation of the sealing faces, which help our delivery inspection standard of zero leakage.
