Direct-acting 2/2-way plunger valve
Type 0293 / Ident No. 256321
Product description
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.
