A hydraulic valve is a device used to control the flow and pressure of hydraulic fluid in a hydraulic system. It is typically made up of a valve body, which contains the necessary ports and passages for fluid flow, and a valve spool or poppet, which is responsible for regulating the flow of fluid.
Hydraulic valves can be classified into various types based on their function and design. Some common types include:
1. Directional control valves: These valves control the direction of fluid flow in a hydraulic system. They typically have multiple ports and can be used to control the movement of hydraulic cylinders or motors.
2. Pressure control valves: These valves regulate the pressure of the hydraulic fluid in a system. They can be used to maintain a specific pressure level or limit the maximum pressure.
3. Flow control valves: These valves control the rate of fluid flow in a hydraulic system. They can be used to adjust the speed of hydraulic cylinders or control the flow to different actuators.
4. Check valves: These valves allow fluid flow in one direction while preventing it from flowing back in the opposite direction. They are commonly used to maintain pressure in hydraulic systems or prevent backflow.
Hydraulic valves are essential components in hydraulic systems, as they enable precise control and efficient operation. They are commonly used in various industries, including manufacturing, construction, agriculture, and automotive.

*ST Titanium indicates that it has been confirmed that the price of titanium dioxide in China has gradually stabilized since the beginning of this year. At present, the price of the company's products will not increase substantially, but the company will produce the main raw material titanium Mine and ** prices are still rising. The subtext seems to be that the company is not only difficult to enjoy the price increase, but also seems to face the pressure of rising costs.
Annada is much more optimistic. The company stated that since the beginning of this year, due to the increase in prices of major raw materials and the increase in product demand, the company’s product sales prices have increased significantly compared with the previous year. To this end, Annada raised its net profit in the first half of the year to 60% to 110%.
Due to rumor that the world's largest titanium dioxide producer has recently increased prices sharply, *ST Tibai and Ananda's share price rose sharply for three consecutive days. * ST titanium dioxide has been a daily limit for 3 days, and Annada’s cumulative gain of up to 27% over the last 3 days. Today, the two companies separately disclosed an announcement of unusually volatile stock prices, explaining the impact of the price of titanium dioxide products, but the views differed.
