Product Overview
The BURKERT 6440 A 8,0 EPDM VA is a direct-acting 2/2-way solenoid valve from Bürkert’s proven Type 6440 series, engineered for precise open/close control of neutral and mildly aggressive media in industrial process and pneumatic systems. The valve operates on a direct-acting principle, meaning the solenoid armature directly actuates the sealing element without requiring a minimum differential pressure, allowing reliable switching from zero bar up to the rated operating pressure. The model designation “A 8,0” indicates an 8.0 mm nominal orifice diameter, while “EPDM” specifies the diaphragm and seal material (ethylene propylene diene monomer) and “VA” denotes a stainless steel (1.4401/316) valve body. This combination makes the 6440 A 8,0 EPDM VA particularly suitable for water treatment, dosing systems, and general industrial fluid control where corrosion resistance and media compatibility are essential.
