The Burkert solenoid valve Type 6213 with article number 221652 is a servo-assisted diaphragm valve, 2/2-way, normally closed (NC). This version has a brass body with internal thread G1/2, orifice DN 10 and EPDM seals.
How the diaphragm valve Type 6213 works
When de-energised, the flow path from port 1 (P) to port 2 (A) is closed; the valve only opens when the coil is energised. In Type 6213, the diaphragm is coupled to the plunger by a spring; this spring coupling assists opening, so the valve already switches from 0 bar. According to the data sheet, a differential pressure of 0.5 bar is needed for the full cross-section; the pressure range extends to 10 bar. The valve closes with damping and operates quietly. The Kv value for water is 1.9 m³/h. According to Burkert, this version opens in 10–30 ms and closes in 100–150 ms.
Coil and electrical connection of Type 6213
The plug-on polyamide coil for 110 V AC 50 Hz (size 32 mm, insulation class B) sits on the centrally screwed pilot stage. The AC coil draws 24 VA at switch-on and 8 VA in holding mode; the rated power is 8 W. It is connected via plug contacts to DIN EN 175301-803 form A; with a cable plug, the valve achieves IP65. The cable plug Type 2518 is not included and available separately.

Applications of Burkert Type 6213
According to the data sheet, the standard version is intended for liquids; it switches media that do not attack the body and seal materials (viscosity max. 21 mm²/s). It can be installed in any position, preferably with the actuator facing up. As a dealer listed by Burkert, we source the valve directly from the manufacturer.
