230 V - 50 Hz. Shuts off mechanically in case of power failure. This valve is installed in combination with Art. B.045, B.050 and B.052.20. Resetting of solenoid valve must be done manually. Max. operating pressure 500 mbar. N.B: For counterflanges Art. V.150,
Supply 9-12 Vdc – Max. pressure: 1.000 mbar. Receiving an electtric impulse from the gas detector, the solenoid valve closes.The installation of this solenoid valve can be matched directly with detector B.038.00 with the independant power line (stand alone) with detectors B.045 - B.050 - B.051 - B.052.
Supply unit: 230 Vac. Output of alarm command: 12Vdc – eventual impulse for solenoid valve. Degree of protection: IP 42 – Catalytic sensor with alarm threshold: 10% LIE
