Membrana Kromschroeder 74924631 do modeli VGBF/VAR/GIK 80 /B

Working diaphragm (membrane) Kromschroder 74924631 for regulators VGBF 80..40 /B, VAR 80 /B and GIK 80 /B is an original spare part designed to restore regulation accuracy and tightness of gas pressure and ratio regulators. This diaphragm is a "working" one — it converts pressure differential into mechanical force to move the valve, ensuring stable output pressure and precise maintenance of set parameters. Installing a new membrane eliminates combustion instability caused by wear or damage to the elastomer. Technical specifications: Parameter Value Part numbers 74924631, 624.478.012 Manufacturer Kromschroder / Honeywell (Germany) Part type Working diaphragm Compatibility VGBF 80..40 /B (gas pressure regulator DN80, up to 4 bar); VAR 80 /B (differential pressure regulator); GIK 80 /B (ratio regulator) Material Perbunan (NBR) — oil and gasoline resistant rubber, resistant to natural and liquefied gas Weight 0.304 kg Warranty 1 year (when purchased from official dealers) Application Natural gas, liquefied gas (propane-butane) Application area and signs of wear: This membrane is used in gas pressure regulators VGBF 80..40 (with inlet pressure up to 4 bar) and gas-air ratio regulators GIK 80 /B, as well as differential pressure regulators VAR 80 /B. All three types of regulators are installed on gas lines before the burner in industrial boiler houses, furnaces and heat generators. Brief information about Kromschroder regulators: VGBF — high pressure regulators with the ability to adjust output pressure in various ranges by selecting appropriate springs. Model VGBF 80..40 /B is designed for output pressure up to 4 bar. GIK — ratio regulators
