Kromschroeder 74924622 VGBF100..05/10; GIK100 /B diafragma

Compensating diaphragm Kromschroder 74924622 for VGBF100..05/10; GIK100 /B is an original elastic element designed to replace a worn part in VGBF 100..05/10 gas pressure regulators (with outlet pressure up to 1 bar) and GIK 100 /B gas-air ratio regulators. This diaphragm is a "compensating" one — it senses changes in inlet pressure and counteracts them, ensuring stable outlet pressure regardless of line fluctuations. Without it, when inlet pressure rises, the valve would lift higher, disrupting settings, making this membrane critical for accurate regulator operation. Technical specifications: Parameter Value; Part numbers 74924622, 624.478.005; Manufacturer Kromschroder / Honeywell (Germany); Part type Compensating diaphragm; Compatibility VGBF 100..05/10 (gas pressure regulator, DN100, up to 1 bar); GIK 100 /B (ratio regulator); Material Perbunan (NBR) — oil and gas resistant rubber; Weight 0.255 kg; Application Natural gas, liquefied gas (propane-butane). ✅ Key advantages: Outlet pressure stability: The compensating membrane neutralizes the effect of inlet pressure surges, ensuring precise maintenance of set outlet pressure. This is critical for stable burner operation and preventing flame blow-off. Gas-air ratio accuracy (for GIK): In GIK 100 /B regulators, this diaphragm ensures stable 1:1 ratio between gas pressure and air control pressure, necessary for efficient fuel combustion and energy savings. Restoring tightness: A new membrane eliminates gas leakage through the vent line (breather valve) or regulator housing, which is critical.
