BURKERT 20036857 (Type 0330) is a direct-acting, media-separated pivoted armature solenoid valve designed for controlling neutral and aggressive media. The coil system is separated from the medium by a diaphragm, making the valve suitable for critical media such as aggressive acids and alkalis. It features a PVDF (Polyvinylidene fluoride) body, FKM (Fluor rubber) seals, and a 3.0 mm orifice. The valve operates within a pressure range of 0 to 10 bar and handles medium temperatures from 0 °C to +80 °C.

The maintenance-free pivoted armature technology and vibration-proof, block-screwed coil system ensure a long service life. The 20036857 model is configured for Circuit Function A (2/2-way, normally closed) and includes a service-friendly, robust manual override for start-up and testing.
