Krom schroder VAS125R/NW 88000571 gas control unit technical data: Inlet: DN 25 (1'') Outlet: DN 25 (1'') Rp internal thread Quick opening, quick closing With flow adjustment Mains voltage: 230 V AC, 50/60 Hz Electrical connection: plug with socket Accessories, right: 2 screw plugs Accessories, left: 2 screw plugs Pu max.0.5 bar Weight: 1,603 kg Kromschroeder 88000571 VAS125R/NW gas control block function: Kromschroder 88000571 VAS125R/NW gas valve closed when it disconnected from the power supply. Opening: connect the system to the electrical power supply (alternating voltage will be rectified). The blue LED lights up. The coil’s magnetic field pulls the armature with the attached valve discs upwards. Krom schroder 88000571 VAS125R/NW gas solenoid valve opens. The double valve seat means that the forces from the inlet pressure divided almost equally between the two valve seats. Closing: disconnect Kromschroder 88000571 VAS125R/NW from the electrical power supply. The blue LED goes out. The armature pressed into its initial position by the closing spring. The gas solenoid valve closes within 1 s. The strainer in the inlet of the gas solenoid valve prevents deposits of dirt particles on the valve seats. The pressure loss through the strainer is very low.
