Kromschroder Gas solenoid valve VAS125R/NW 88000005

Kromschroder VAS125R/NW gas solenoid valve with SKU 88000005, designed for safeguarding and controlling air and gas supply in gas burners and appliances. It features a double valve seat, operates at 230 V AC, and has a maximum pressure of 0.5 bar. The valve includes RP internal thread connections, flow adjustment, and comes with 2 screw plugs on each side. It closes within 1 second, indicated by a blue LED that lights up when energized and goes out when de-energized. The electrical connection is via an M20 cable gland, and the valve weighs 1.603 kg.

Parts of this type are selected by matching the valve's nominal size (DN range from 10 to 65, with DN 40 and 50 available) and thread type (RP internal thread) to the existing piping. Ensure the coil voltage (e.g., 230 V) and maximum pressure rating (e.g., 0.5 bar) are compatible with the system. The valve may have threaded or flanged connections; verify the connection type and size before ordering. Installation involves connecting the electrical supply (alternating voltage will be rectified) and ensuring proper sealing with the provided screw plugs.

Common failures include the valve not opening or closing properly, often due to coil burnout or debris blocking the valve seat. If the blue LED does not light up when power is applied, the coil may be faulty. If the valve fails to close within 1 second, the closing spring or armature may be worn. Check for voltage at the coil and inspect the valve for contamination or mechanical damage.
