Kromschroder Gas solenoid valve VAS115R/NW 88000003

The Kromschroder VAS115R/NW gas solenoid valve (SKU 88000003) is a double valve seat unit with an RP internal thread, designed for pipe connections from DN10 to DN65, including DN40 and DN50. It operates at a coil voltage of 230 V AC, with a pressure range of 0–500 mbar and a maximum pressure of 0.5 bar. The valve features a blue LED that lights up when energized and goes out when de-energized, and it closes within 1 second. It includes flow adjustment, M20 cable gland electrical connection, and 2 screw plugs on each side. The valve weighs 1.551 g and has an outlet connection of DN15 (1/2'').

Parts of this type are selected by matching the coil voltage, pressure range, and connection size to the existing system. The valve type (e.g., double valve seat) and thread type (e.g., RP internal) must correspond to the piping. Before ordering, verify the inlet and outlet diameters, electrical connection type, and whether accessories like screw plugs are needed. Mounting forms include threaded or flanged connections, with flanged options for DN40 and DN50.

Common failure modes for such valves include coil burnout, leading to the valve not opening or closing properly. The blue LED may fail to light or stay lit, indicating electrical issues. If the valve does not close within 1 second, the closing spring or armature may be worn. Check the electrical supply and connections, and inspect the valve seat for debris or damage.
