Liaoyang Valve Valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids. The working pressure of the valve can be from 0.0013MPa to 1000MPa ultra-high pressure. The working temperature ranges from an ultra-low temperature of -269°C to a high temperature of 1430°C. The valve can be controlled by a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, pneumatic-hydraulic, spur gear, bevel gear drive, etc.; it can be driven by pressure and temperature. Under the action of other forms of sensing signals, it will act according to the predetermined requirements, or simply open or close without relying on the sensing signals. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate Movement, thereby changing the size of the flow channel area to achieve its control function.

 

The valve manufacturing industry is bound to present a better development prospect under the huge demand environment. At present, the turnover of my country's valve market is as high as 50 billion yuan, which fully demonstrates the scale and momentum of the development of my country's valve industry. However, in the context of a good industrial situation, there are also some problems worthy of our worry, especially the valve companies in my country are mainly low-level, small-scale, family-based enterprises. This is a big limitation and bottleneck for the future development of my country's valve industry. At present, domestic key valve manufacturers have been able to design and manufacture various valves in accordance with international standards such as ISO international standards, DIN German standards, AWWA American standards, and some manufacturers' products have reached the international advanced level. Although the overall level of the valve industry in the New Year has been greatly improved, the quality is not stable enough, such as running, leaking, dripping, and leakage often appear in domestic valves. In addition, there is still a certain gap between my country's valve supporting capabilities and developed countries. Competition in the valve market is becoming more and more fierce. Some common valve product markets have been saturated and supply exceeds demand. This makes the development of small and medium-sized enterprises more and more difficult. And even high-tech products compete fiercely in the international market.
