The lift check valve is a unidirectional flow control device that automatically opens and closes via medium pressure to prevent backflow, widely used in industrial and civil pipeline systems. Its core structure comprises a valve body, disc, seat, and guiding mechanism, operating on the balance between fluid pressure and the disc's gravitational force. When media flow forward, the fluid pressure overcomes the disc's gravity, pushing it vertically upward off the seat sealing surface to open the passage with minimal resistance. Once the flow stops or reverses, the disc drops onto the seat under gravity and backpressure, forming a tight seal to bloc

A pneumatic fluorine-lined control valve is a specialized flow control device designed for highly corrosive media. Driven by compressed air, it receives 4-20mA electrical signals or 0.02-0.1MPa pneumatic signals to actuate the valve plug, enabling precise regulation of fluid flow. The valve body, plug, and seat are coated with fluoropolymers like polytetrafluoroethylene (PTFE), which resist almost all strong acids, alkalis, and oxidants, operating stably within -30°C to 70°C.

Its structural design is exquisite, and the sphere is firmly fixed inside the valve body through upper and lower shaft necks, even in the face of high-pressure fluid impact, it can maintain stable position without displacement. The valve seat adopts a floating design, usually composed of metal seat rings, sealing rings, rubber O-rings, springs and other components. During operation, the pressure of the medium pushes the valve seat to tightly fit the sphere, while the spring provides additional preload force, ensuring a bi-directional sealing effect and achieving bi-directional sealing upstream and downstream. There is no need to worry about flow direction during installation. For example, in long-distance natural gas pipelines, the stable structure of hard sealed fixed ball valves ensures long-term reliable operation under complex pressure environments.
