Kromschroder Seal set 74926010

This seal set is a repair kit for Kromschroder RV(S) 2..ML.../B gas control valves. It contains sealing rings (o-rings) and gaskets. The kit is used to replace worn seals during scheduled maintenance, restoring tightness and preventing leakage. It is manufactured in Germany and complies with EN 746-2. The kit carries a 1-year warranty.

Seal sets of this type are matched to a specific valve series, so the fitter must confirm the valve model and the medium (natural gas, LPG, or air) before ordering. The set includes all static sealing surfaces for that series. Installation must be done by qualified personnel after shutting off the gas and releasing line pressure to atmospheric pressure. After installation, check the tightness of all connections using soap solution or a gas analyzer.

Seals of this type harden or deform over time from heat, vibration, and chemical exposure to the gas. This can cause gas leakage through the valve in the closed position, unstable burner operation, or inability to adjust the gas flow precisely. Damage may be visible on the seals, or leaks can be detected using soap solution. Periodic inspection is recommended to catch such wear early.
