Pressure Seal Check Valve
A pressure seal check valve is a type of check valve that uses a pressure seal to prevent backflow. The valve features a pressure-assisted seal that is designed to close tightly against the valve seat, preventing backflow and ensuring a tight seal. These valves are typically used in high-pressure and high-temperature applications, such as power plants and chemical processing plants. They are also commonly used in pipelines and other fluid systems where a tight seal is required to prevent leakage.
