BURKERT 20035090 (Type 0331) is a direct-acting, media-separated pivoted armature solenoid valve. It is configured as a 3/2-way valve with circuit function T (for universal use, flow direction optional). The solenoid actuator and the medium chamber are separated by a diaphragm system, making it highly suitable for critical or aggressive media. This specific model features a brass body, EPDM seal, 2.0 mm orifice, and a Bürkert specific flange connection. It operates at 24 V (50/60 Hz AC) and supports a pressure range of 0 to 12 bar.
