Burkert Type 6212 Diaphragm Valve with servo-diaphragm and 3-way pilot control with medium separation. Available in the circuit functions NC and NO. The medium separation in the pilot valve enables the valve to be used for slightly aggressive medium. (e. g. deionised water).
Burkert Type 6212 Diaphragm Valve Features
- Media separated
- Reduced power consumption
- Stainless steel housing for aggressive media
- Circuit function NC or NO
