Product Features
Double-Disc Structure: Adopting a double-valve disc design, it can quickly respond to the forward and reverse flow of fluid, ensuring reliable sealing performance.
Strong Corrosion Resistance: The Aluminum Bronze material has excellent seawater corrosion resistance, and is especially suitable for offshore engineering and the chemical industry.
Compact Design: The wafer connection method saves space and is convenient for installation and maintenance.
High-Efficiency Sealing: Metal-to-metal sealing is adopted between the valve disc and the valve seat to ensure zero leakage.
Quick Installation: The wafer connection method does not require flanges, making installation simple and saving time and cost.
Application Areas
Offshore Engineering: Used in seawater pipeline systems to prevent seawater backflow.
Chemical Industry: Suitable for the transportation of corrosive media such as acids, alkalis, and salts.
Water Treatment Systems: Used to prevent water backflow and protect pumps and pipeline systems.
Petroleum and Natural Gas Industry: Used for transporting media such as petroleum and natural gas to ensure the safe operation of pipeline systems.
Industrial Fluid Systems: Applicable to the control of various industrial fluids such as cooling water and steam.
Installation and Maintenance
Before Installation: Check whether the inside of the valve is clean and make sure there is no impurity blocking the valve disc. Check whether the connection parts are intact.
During Installation: Ensure that the fluid flow direction is consistent with the arrow mark on the valve body. When using the wafer connection method, make sure that the pipeline flanges are aligned with the valve and tighten the bolts evenly.
Maintenance: Regularly check the sealing performance of the valve. If there is leakage, replace the sealing parts in time. Regularly clean the impurities inside the valve body to ensure the normal operation of the valve.
