Burkert 47859 Media-Separated Solenoid Valve (Type 0121)
The Burkert 47859 is a direct-acting 2/2-way pivoted armature solenoid valve from the high-performance Type 0121 series. Engineered with complete fluid isolation, its media-separated diaphragm prevents process media from coming into contact with the solenoid system, providing outstanding operational security when handling aggressive, pure, or particulate-laden liquids and gases.
