Kromschroeder 74924644 GIK65 /B safety diaphragm

Kromschroder 74924644 protective diaphragm (Compensating Diaphragm) for GIK 65 /B — an original elastic element used in GIK 65 /B gas-air ratio regulators for precise compensation of inlet gas pressure fluctuations. Unlike the main working diaphragm, this diaphragm ensures outlet pressure stability regardless of pressure variations at the regulator inlet. In Kromschroder GIK regulators, a system of two diaphragms is installed. The main diaphragm controls valve opening based on the air pressure signal. The auxiliary (compensation) diaphragm, as in this kit, neutralizes the effect of gas pressure fluctuations on the main valve. Without this function, as inlet pressure rises, the valve would lift higher, disrupting settings; the diaphragm compensates for this force, maintaining stable outlet pressure. Technical specifications Part numbers: 74924644, 624.478.003 Manufacturer: Kromschroder / Honeywell (Germany) Part type: Protective / Compensation diaphragm (Compensating diaphragm) Compatibility: GIK 65 /B (gas-air ratio regulator DN65) Material: Gas-resistant elastomer Purpose: Compensation of inlet gas pressure (Pe) fluctuations Weight: 0.010 kg (10 g) ✅ Key advantages Stability of gas-air ratio: The compensation diaphragm neutralizes the effect of inlet gas pressure surges on the regulator outlet. This ensures precise maintenance of the set 1:1 ratio between gas and air pressure, which is critical for efficient fuel combustion and protection against ignition pops. Protection against pressure fluctuations: The diaphragm prevents transmission of overloads from the main valve to the working diaphragm, protecting it from premature wear and rupture. This is especially important in systems with unstable inlet pressure.
