Kromschroder Repair kit (Service Kit / Spare Part Pack) 74922193

Kromschroder Repair kit (Service Kit / Spare Part Pack) 74922193 is a spare part set for gas pressure regulators of the VGBF50..40 series. It includes diaphragms, o-rings, gaskets, and technical lubricant. The kit is designed for scheduled maintenance to restore tightness and accuracy of the regulator. It weighs 144 g.

Parts of this type are selected by matching the regulator series designation, such as VGBF50..40. Before installation, isolate the gas supply and depressurise the valve body. Disassemble according to manufacturer's instructions, clean mating surfaces, and install new parts in correct orientation. After reassembly, test for leaks and check operational pressure range.

Worn diaphragms and gaskets in gas regulators can cause unstable output pressure, gas leaks, or intermittent burner operation. Leaks may occur through the impulse tube or regulator breather valve. Regular replacement of these components prevents emergency shutdowns and extends equipment life.
