The latest development of copper valve technology
2021/06/24
Since the beginning of the 21st century, some well-known domestic copper valve manufacturers have broken conventional ideas and bravely innovated and practiced, and have developed a large number of new products, which greatly improved the scope of application of copper valves in engineering applications. In particular, the successful experimental development of the all-copper hydraulic control series has not only made a qualitative leap in the manufacturing process of copper valve products, but also greatly promoted the overall competitiveness of the copper valve industry.

The development direction of special metal bellows materials for copper valves
The material of the copper valve suitable for the production of bellows must have good plasticity, high elastic limit, tensile strength and fatigue strength, good welding performance, and stable elastic performance. Because of these performance characteristics, austenitic stainless steel is widely used in the manufacture of bellows.

What is a parallel double gate valve? Main material of double gate valve
What is a parallel double gate valve? Parallel double gate valve is also called rising stem gate valve. When opened, the valve stem is exposed to the outside of the valve body and moves up and down. The stem nut is located on the valve cover or bracket, even if the nut rotates, the stem will not rotate, and the opening/closing part will move up and down to open and close the valve.
