Gate Valve Overview Gate valves are an indispensable equipment in the industrial field and are widely used to control the flow of liquids and gases. It works by allowing or blocking the flow of fluid through a gate (or wedge) that rises and falls. In the closed state, the gate is effectively sealed with the seat, preventing the flow of fluid completely. This design allows gate valves to provide excellent sealing and the lowest pressure drop when fully opened, which is why they are favored. Whether...

Full bore check valves, also known as full-port check valves, are an important fluid control device specifically designed to prevent backflow without significantly limiting flow. It ensures that the fluid maintains maximum flow efficiency in the piping system while minimizing pressure drop. The working principle of the full bore check valve is: when the inlet pressure exceeds the outlet pressure, the valve automatically opens to allow the fluid to flow forward; When the outlet pressure is higher...

The demand for natural gas in daily production and life is increasing with the improvement of the social economy. Natural gas is a clean, pollution-free energy source and is widely used worldwide. However, the distribution of natural gas in China is uneven. Natural gas resources are relatively scarce in the economically developed eastern region of China, while in contrast, the sparsely populated western region is rich in natural gas resources. Therefore, to promote economic development effectively,...
