Kromschroder Gas solenoid valve VAS240R/NW 88000024

The Kromschroder VAS240R/NW is a normally closed gas solenoid valve with a 230 V AC coil, designed for use in gas distribution systems. It features threaded flanges with Rp internal thread connections, suitable for pipelines with nominal diameters from DN 10 to DN 65, and specifically for DN 40 and DN 50 with flanged sizes 2 and 3. The valve includes a flow adjustment mechanism, an M20 cable gland for electrical connection, and two screw plugs on each side. A blue LED indicator lights up when the valve is energized, and the valve closes within 1 second after power is removed.

When selecting a replacement gas solenoid valve of this type, ensure the coil voltage matches the system's supply (e.g., 230 V AC). Verify the connection type and thread size (e.g., Rp internal thread) against the existing piping, and confirm the valve's nominal diameter range (e.g., DN 10 to DN 65) is compatible with the pipeline. Check the electrical connection type (e.g., M20 cable gland) and the presence of accessories like screw plugs. The valve's flow adjustment feature should be considered if precise gas flow control is required.

Common failures of gas solenoid valves include coil burnout, which may cause the valve to remain closed or fail to open, and debris accumulation on the seats, leading to incomplete closure or leakage. A faulty coil may result in no LED indication when power is applied, or the valve may not open despite the LED lighting. Check the coil resistance and ensure the valve is clean and free of obstructions.
