C87300 silicon bronze is a copper alloy with high silicon content and has excellent application properties. The following are the main application properties of C87300 silicon bronze:

• Wear resistance: C87300 silicon bronze has excellent wear resistance, especially suitable for the manufacture of wear parts and friction pairs. Its silicon content can form hard silicides, enhance the hardness and wear resistance of the material, and improve the service life of the parts.
• Corrosion resistance: C87300 silicon bronze has excellent corrosion resistance and can resist the erosion of corrosive media, including acid, alkali, salt and so on. Therefore, it is often used in the manufacture of chemical equipment, Marine equipment and water treatment equipment.
• Thermal conductivity: C87300 silicon bronze has good thermal conductivity and can quickly conduct heat to other components or the environment, so it is widely used in thermal components and radiators and other fields. At the same time, its thermal conductivity also makes the material advantageous in the manufacture of electronic devices and electrical connectors.
• Oxidation resistance: C87300 silicon bronze can maintain good oxidation resistance at high temperatures and is not easy to oxidize. This makes it suitable for applications in high temperature environments such as stoves, heat exchangers and boilers.
• In general, C87300 silicon bronze has excellent application properties such as wear resistance, corrosion resistance, thermal conductivity and oxidation resistance, and is widely used in various industrial fields, including chemical, Marine, electronics, energy and so on.

Three-way valve features

1. Three-way valves have two spool and seat structures similar to two-seat valves, but in three-way valves, when the flow area between one spool and the seat increases, the flow area between the other spool and the seat decreases. In the two-seat valve, the flow area between the two spool and the seat increases or decreases at the same time.

2. The gas opening and gas closing of the three-way valve can only be realized by selecting the positive and negative action of the power machinery, while the gas opening and gas closing of the two-seat valve can be realized directly by the valve body or the spool and the seat.

3. When the three-way valve is used in a control system that requires fluid matching, it can reduce installation costs and reduce installation space because it can replace a gas open control valve and a gas close control valve at the same time.

4. Three-way valves can also be used in bypass control places, such as one fluid needs to pass through the heat exchanger heat transfer, the other fluid does not need to pass through the heat exchanger heat transfer, when the three-way valve is installed in front of the heat exchanger, the shunt three-way valve is used when the three-way valve is installed in the heat exchanger after the combined three-way valve. Because the liquid flowing through the three-way valve installed in front of the heat exchanger has the same temperature, the leakage is small, and the liquid flowing through the three-way valve installed after the heat exchanger has different temperatures, and the expansion degree of the valve core and the seat is different, so the leakage is large. Generally, the temperature difference between the two liquids should not exceed 150 degrees.
