Description

The Kromschroder Compensating membrane 74924629 is an original spare part for the VGBF 100..40 /B gas pressure regulator. It is made of perbunan (NBR) and operates within an ambient temperature range up to 60 °C. This membrane compensates for inlet pressure fluctuations, ensuring stable outlet pressure and restoring regulator tightness and accuracy. Its EAN code is 4031624746292.

Further details

Application	gas pressure regulators VGBF 100..40 installed on gas trains before the burner in industrial boiler houses, furnaces, and heat generators
Inspection before install	inspect valve seat and diaphragm contact surface for debris or scoring; check diaphragm for cracks, permanent set, or hardening
Installation notes	handle by edges, ensure even seating, torque retaining screws to spec, test for leaks after reassembly
Material suitability	correct material for gas type (natural gas, LPG, biogas)
Replacement benefit	restores tightness and accuracy of the gas pressure regulator, eliminates combustion instability
Signs of wear	unstable outlet pressure, external gas leaks, sticking of the regulating mechanism, pressure mismatch

Choosing and fitting

Parts of this type are selected by matching the valve series and nominal size, as well as the pressure rating and gas type compatibility. Before ordering, verify the exact valve model and its data plate specifications. During installation, handle the diaphragm by its edges, ensure it seats evenly, and torque retaining screws to manufacturer specifications.

Signs of failure

Wear or damage to this kind of membrane can cause unstable outlet pressure, external gas leaks through the vent line or housing, sticking of the regulating mechanism, or pressure mismatch. Check the diaphragm for cracks, permanent set, or hardening, which can lead to leakage or erratic modulation.
