The gate valve has a small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change
its flow direction when flowing through the gate valve. The torque required for opening and closing is small, the body structure is simple, the
manufacturing process is better, the sealing performance is good, and the corrosion of the dense cover when the full opening is less. The scope of
applications is wide. Because the phenomenon of the long water hammer is not easy to occur. The medium can flow in any direction on both sides
and easy to install.
Application Scenarios: The wedge valve is generally used in the shape of the valve's shape without strict requirements, but the use conditions are
more harsh. For example, a high-temperature and high pressure working medium, toxic and harmful risk liquids require closure to ensure
long -term sealing and leakage. Under normal circumstances, the requirements for use requirements are reliable. Such as the application of power
industry, petroleum refining, petrochemical industry, marine oil, tap water engineering in urban construction, chemical industry and other fields.

Oxygen Globe Valve are often used in physical and chemical experiments with gases such as oxygen, nitrogen, hydrogen, argon, etc. These gases are usually stored in dedicated high-pressure gases. When in use, the gas pressure is reduced to the required range for the experiment through a pressure reducing valve, and then finely adjusted through other control valves to input the gas into the system. The oxygen shut-off valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
C700 Series Single Seated Control Valve is a top-guided structure control valve, used in equipment that can achieve air opening or air closing. The fluid channel of the valve body is in an S-shaped streamlined shape, featuring low pressure drop loss, large flow rate, wide adjustable range, high accuracy of the flow characteristic curve, large guiding area of the valve core, and good vibration resistance. The control valve is equipped with a multi-spring diaphragm actuator, which features a compact structure and large output force. It can be used to control various fluids with different pressures and temperatures.
