Type 293 switches without pressure difference from zero bar. The valve is especially good for switching low-pressure combustible gases.The direct-acting solenoid valve is delivered with circuit function A. It is normally closed. Upon switching, the magnetic core is tightened against the spring and the valve opens. A filter is built-in to the inlet. A dirt trap = 500 µm (example our type TFU001) needs to be installed before the valve when using DN 25. This dirt trap needs to be accessible for maintenance. For selecting the correct product please refer to the technical data, images and notes for proper use according to the data sheet.
