Diaphragm material plays a vital role in the sealing efficiency of the valve and its compatibility with different applications. Flexible diaphragms, such as EPDM (ethylene propylene diene monomer) or silicone, are typically used in applications involving low to moderate temperatures and non-corrosive fluids.
The sealing principle of the sanitary diaphragm valve also enables it to be used in bi-directional flow applications. This means that the valve can be installed in piping in any direction, enabling it to meet a wide range of process requirements.
However, potential limitations of sanitary diaphragm valves must be considered. High-pressure applications may require larger, more robust actuators to ensure adequate sealing force.
