Kromschroder Gas solenoid valve VAS240/-R/NW 88000094

The Kromschroder VAS240/-R/NW gas solenoid valve (SKU 88000094) is a normally closed valve with a 230 V AC coil. It features threaded flanges with Rp internal thread and includes two screw plugs on each side. The valve has an M20 cable gland for electrical connection and a blue LED indicator that lights up when energized. It is designed for quick opening and closing with flow adjustment capability.

When selecting a replacement valve of this type, ensure the coil voltage matches the system (e.g., 230 V). Verify the connection type and thread size (Rp internal thread) to fit the existing piping. Check the valve's nominal diameter compatibility with the pipeline (DN 10 to DN 65, with specific flanged sizes for DN 40 and DN 50). Confirm the electrical connection type (e.g., M20 cable gland) and that the valve is normally closed as required.

Common failures include coil burnout, which prevents the valve from opening when voltage is applied, indicated by the LED not lighting. Valve sticking may occur due to debris, causing failure to close within 1 second after power removal. Check the inlet screen for blockage and verify the coil continuity with a multimeter.
