Multi-Media Compatibility

Lokval Flow pneumatic control valve uses highly corrosion-resistant valve body material, and the valve seat and diaphragm material of the pneumatic control valve can be selected according to different application characteristics, providing you with high chemical resistance material options including PTFE, EPDM, FPM (Viton), PFA lining and other high chemical resistance materials.

The Lokval Flow pneumatic control valve can be used for a series of special media including hydrochloric acid, sulfuric acid, hydrofluoric acid, alkali, volatile, high viscosity, suspended media and so on.

Low Maintenance, High Performance

Lokval Flow pneumatic control valves are designed to handle highly corrosive media and maintain performance over time. They have a certain self-cleaning ability, reducing the need for frequent maintenance. The simple design makes maintenance easier, thereby reducing downtime and maintenance costs. This allows your automation system to have a longer service life and higher operating efficiency.
