Product Overview
The Bürkert Type 2873 (model code 2873 A 2,5 EPDM VA / 00255671) is a direct-acting 2/2-way proportional solenoid valve engineered for precise, continuously variable control of neutral and slightly aggressive media in industrial process and pneumatic systems. As part of Bürkert’s 2873 series, this valve modulates flow or pressure proportionally to the electrical current applied to its solenoid coil, rather than operating in a simple on/off manner. The “A” designation indicates a normally closed (NC) circuit function, while the “2,5” refers to a nominal orifice size of 2.5 mm. The EPDM seal material and VA (stainless steel) body construction make this valve suitable for use with water, neutral liquids, and compatible process media where corrosion resistance and media purity are essential. Its compact, direct-acting design allows reliable operation from zero differential pressure, making it a versatile control element in dosing, mixing, and flow regulation applications across process automation and industrial hydraulic circuits.
