Kromschroder Gas solenoid valve VAS350R/LQ 88000055

The Kromschroder VAS350R/LQ gas solenoid valve, SKU 88000055, is a size 3 valve with a double valve seat, designed for safeguarding and controlling air and gas supply in gas burners and appliances. It features a 120 V AC coil, operates at 50/60 Hz, and has an RP internal thread with DN 50 (2'') inlet and outlet. The valve includes 2 screw plugs on each side, an M20 cable gland, and a blue LED indicator. It provides low opening and quick closing, with the valve closing within 1 second upon power disconnection.

When selecting a replacement valve of this type, ensure the coil voltage, frequency, and electrical connection match the system. Verify the valve size, thread type (RP or NPT), and inlet/outlet diameters (DN range from DN10 to DN65, with DN40 and DN50 for flanged connections) to fit the existing piping. Check the mounting orientation and available space for the cable gland and screw plugs.

Common failures include coil burnout, which may cause the valve to remain closed or fail to open, and LED malfunction indicating power issues. If the valve does not close within 1 second, the closing spring or armature may be worn. Check for debris or damage on the valve seats that could prevent proper sealing.
