Kromschroder Solenoid gas valve VAS110R/NW 88000002

The Kromschroder Solenoid gas valve VAS110R/NW (SKU 88000002) is a normally closed, dual-seat design valve with a coil voltage of 230 V. It features threaded flanges with an inlet connection of DN 10 (3/8'') and is suitable for pipelines with nominal diameters from DN 10 to DN 65. The valve has a maximum pressure of 0.5 bar, a closing time of 1 second, and quick opening with flow adjustment. It includes a blue LED indicator and is equipped with 2 screw plugs on both left and right accessories. The valve operates when alternating voltage is applied, and closes when power is removed, with the blue LED going out.

Parts of this type are selected by matching the coil voltage, connection type, and nominal diameter to the existing system. The flange size (2 or 3) must correspond to the pipe DN (40 or 50). The electrical connection is via an M20 cable gland, and the thread type is Rp internal. Ensure the maximum pressure rating (0.5 bar) is not exceeded. Installation involves connecting the threaded flanges and wiring the coil to the appropriate voltage source.

Common failures include coil burnout, which prevents the valve from opening, and debris accumulation on the seats, causing leakage or slow closing. If the valve fails to open, check the coil voltage and the rectifier with voltage limiter. If it fails to close within 1 second, inspect the spring and seats for wear or contamination. The blue LED not lighting up indicates a power or coil issue.
