Kromschroder Solenoid gas valve VAS125R/NK 88000612

The Kromschroder Solenoid gas valve VAS125R/NK (SKU 88000612) is a normally closed, electrically operated gas valve with a nominal diameter of 25 mm and a connection thread of Rp 1". It operates with a supply voltage of 24 V DC and has a maximum inlet pressure of 500 mbar. The valve is EU certified and features a plug with socket electrical connection. Its net weight is 1.603 kg. This valve is designed for use in gas control systems for industrial applications such as metallurgy, glass, ceramics, public utilities, and food production.

When selecting a solenoid gas valve of this type, ensure the nominal diameter and connection thread match the existing pipeline. The valve size (e.g., size 1) and the pipeline diameter range (DN 10 to DN 65) must be compatible. For flanged connections, verify that the valve size corresponds to the required pipeline diameter (e.g., DN 40 or DN 50 for sizes 2 and 3). Also, confirm the supply voltage and electrical connection type match the system's control circuit. Installation should be performed by a qualified technician, following the manufacturer's guidelines for proper orientation and torque.

Common failure modes for solenoid gas valves include coil burnout, which prevents the valve from opening, or debris blocking the valve seat, causing incomplete closure or leakage. Symptoms may include the burner failing to ignite, irregular flame, or gas odor. Check the electrical supply to the coil, inspect the valve for physical damage, and verify that the inlet pressure is within the specified range. If the valve does not open or close properly, it may need to be replaced.
