Description
Type 293 switches from zero bar without pressure difference. The valve is preferably suitable for switching flammable gases with low pressures. The direct-acting through-magnet valve is supplied in mode A. It is closed without current. When shifting, the magnet core is tightened against a spring and opens the valve. A screen is installed in the inlet. At nominal diameter 25 <, a dirt trap that is accessible for maintenance purposes = 500 µm, for example our type TFU001, must be installed in front of the valve.

Hints
The kv factor indicates the volume flow through a valve, measured in litres/min at 1 bar and at a water temperature between 5 and 30°C. The QNn factor indicates the gas volume flow, measured in litres/min
