Kromschroder Gas solenoid valve VAS125R/NW 88001197

The Kromschroder VAS125R/NW is a normally closed gas solenoid valve with a nominal diameter of 25 mm and a connection thread of Rp 1". It operates at a supply voltage of 230 V and 50 Hz, with a maximum inlet pressure of 500 mbar. The valve features a double valve seat for even pressure distribution, a blue LED indicator, and an inlet screen. It closes within 1 second when power is off and includes auxiliary devices such as 2 screw plugs. The valve is suitable for pipelines with a diameter range of DN 10-65 and has flanged connections for DN 40 and DN 50.

When selecting a replacement gas solenoid valve of this type, ensure the nominal diameter, connection thread, and supply voltage match the existing system. Verify the maximum inlet pressure rating is sufficient for your application. The valve may have threaded or flanged connections; measure the pipeline diameter and check the flange size to confirm compatibility. Also, confirm the electrical connection type and any auxiliary devices required.

Common failures of gas solenoid valves include coil burnout, which prevents the valve from opening, or debris blocking the valve seat, causing incomplete closure or leakage. If the valve fails to open, check the electrical supply and coil resistance. If the valve does not close properly, inspect the seat for damage or contamination. A stuck valve may result in gas flow issues, leading to burner ignition problems or unsafe operation.
