Kromschroder Gas solenoid valve VAS115R/LW 88000008

The Kromschroder VAS115R/LW gas solenoid valve (SKU 88000008) is a normally closed valve used for safeguarding and controlling air and gas supply in gas burners and appliances. It operates on 230 V AC, with alternating voltage rectified internally. When energized, the coil's magnetic field lifts the armature, opening the valve; when de-energized, a closing spring closes it within 1 second. The valve features slow opening and quick closing, an inlet strainer, and a blue LED indicator that lights when powered and goes out when closed. It has Rp internal thread connections (DN15, 1/2") and a maximum pressure of 0.5 bar, with a weight of 1.751 kg.

When selecting a replacement gas solenoid valve of this type, ensure the coil voltage, connection size (DN15, Rp internal thread), and maximum pressure rating match the system requirements. Verify the electrical connection type (e.g., M20 cable gland) and that the valve's opening/closing characteristics (slow opening, quick closing) are suitable for the application. Check the inlet and outlet connections for compatibility, and confirm the valve is normally closed when de-energized. Measure the physical dimensions and thread type to ensure proper fit.

Common failures of gas solenoid valves include coil burnout, which may cause the valve to fail to open or close, leading to no gas flow or continuous flow. A stuck armature due to debris or wear can result in incomplete closure, causing gas leakage. The blue LED may not light if the coil is faulty or the electrical connection is loose. Check the inlet strainer for clogging, which can restrict flow and increase pressure loss. If the valve does not close within the specified time, inspect the closing spring and armature movement.
