6228 2/2-Way Diaphragm Solenoid Valve
Brand: Burkert Fluid Control Systems
The Type 6228 is a servo-assisted 2/2-way solenoid valve with servo-diaphragm. It is particularly suited for neutral media.
Without electrical power, this solenoid valve is closed. Pressure builds up through the servo diaphragm, which pushes the latter downwards and thereby keeps the valve closed.
On switching, the space above the servo-diaphragm will be relieved via the pilot valve. As a result, the pressure of the medium lifts the servo-diaphragm, and the main valve opens.
A minimum differential pressure of psi: 7.252 (kPa: 50, bar: 0.5) is required for complete opening and closing. The special design and geometry of the internal parts of the valve produce a soft closing function with very low pressure peaks only. It is very simple to extend the valve radially.
