Kromschroder Gas solenoid valve VGP25R01W6 85296300

The Kromschroder VGP25R01W6 gas solenoid valve, SKU 85296300, is a normally closed, fast-acting shut-off valve for gas-consuming installations. It has a nominal diameter of 25 mm with Rp 1" connection thread, operates at 230 V supply voltage, and handles a maximum inlet pressure of 150 mbar. The valve opens in 0.5 seconds and closes in 1 second, with an ambient temperature range of -20 to 60 °C and IP54 ingress protection.

When selecting a replacement gas solenoid valve of this type, verify the connection size (e.g., Rp 1") and coil voltage (e.g., 230 V) match the existing installation. Check the valve's function (fast-acting or slow-opening) to ensure it does not alter the burner start sequence. Mounting can be vertical, horizontal, or at an angle, but avoid turning the coil upside down; maintain at least 20 mm clearance from walls or floors. Ensure the valve is not installed outdoors.

Common failures include coil burnout, leaking valve seat, drifting outlet pressure, or a seized servo regulator. Symptoms may include the burner failing to ignite, gas flow continuing when it should stop, or inconsistent flame behavior. Check the coil for continuity, inspect the seat for debris or wear, and verify the valve opens and closes fully.
