BURKERT 20016938 (Type 6027) is a direct-acting 2/2-way plunger solenoid valve designed for high-pressure applications. To enhance pressure resistance and leak-tightness, the stopper and plunger guide tube are welded together. This specific model features a stainless steel body, an oxide ceramics seat seal, and is capable of handling gas pressures up to 250 bar and liquid pressures up to 200 bar. It is equipped with energy-saving Kick and Drop double-coil technology and holds ATEX and IECEx explosion-proof certifications, making it suitable for hazardous locations.
