Normally Closed Diaphragm Valve (NC)
Feature:
- Closing valve: the pressure control source is connected with the upper control chamber, the diaphragm pushes the valve seat through the valve stem, thereby cutting off the water to close the valve.
- Opening valve: the pressure control source is connected with the lower control chamber, the pressure in the upper and lower chambers of the diaphragm is balanced, and water pushes the valve stem through its own pressure, so that cavity is easily formed and water is passed.
- Working pressure: 1-8bar
- Working temperature: 4-50°C
