Burkert Chemical Resistance
Materials used in the construction of Burkert Solenoid Valves are carefully chosen to help ensure chemical compatibility with the media you intend to use in your process application.
Chemical resistance is crucial to system designers, engineers and installers; especially when dealing with aggressive fluids and the fact that Burkert Solenoid Valves can be found in many different sectors.
These include: water supply, waste water treatment, machine and plant engineering, building services, safety engineering, compressors, fuel supply, firing systems, gas chromatography, blood analysis instruments, sterilisers, general process engineering, textile industry, domestic installations, biogas plants, car washes, rail, motor and shipbuilding.
Take a closer look at the table below which gives you a brief insight into the chemical resistance properties relating to gasket and housing materials used in the construction of Burkert Soelnoid Valves.
