API gate valves

1.Parallel double-wedge design, adapt to temperature changes, no worry of being jammed, the spring pressure enhancement ensure the both-sealing even in the low pressure.

2.The special structure design of water sealing of packing portion, when connect pressure of 0.6-1.0 MPa water, the system automatically  

Isolate from the air which gives the outstanding character of sealing preventing the decrease of the level of vacuum lead by leakage.

3. The outside of the shell forged critically and precisely is smooth and homogeneous. It can fill the requirement of high, middle and low pressure.         

4.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.

5.The contra-sealing design protects the packing avoiding any leakage of the valve.

6.High water pressure shell test, high gas pressure shell test and audit of damage which generally control the quality of valve.

7.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.

8.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.

9.Our strict manually burnishing assures the 90 percents inosculation of the sealing faces in the two sides which help our delivery inspection standard of bubble level sealing.

10.Varies smart electric actuator domestic and abroad for you to choose from, easily realize online remote controlling and timely information feedback.
