Wedge Gate Valves

1. We take forging and casting technics to make the shell whose outside is smooth and homogeneous. It can fill the requirement of middle and low pressure.                                                        

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. The contra-sealing design protects the packing avoiding any leakage of the valve.
4. Double-wedge design, sealing faces 100 percents inosculation, it is very convenient to maintain and repair on line.

5High water pressure shell test, high gas pressure shell test and aud it of damage which generally control the quality of valve.
6The 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.

7We 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.
8.,Both heading pressure bear sealing design can satisfy the various special work conditions
9.,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.All types of auto-control and intelligent electric actuators can meet your need. They can perform remote auto self-control and auto-inspecting.
