Kromschroeder 74924630 VGBF/VAR/GIK65/B Arbeitsmembran

Working diaphragm (membrane) Kromschroder 74924630 for regulators VGBF/VAR/GIK 65 /B is an original spare part designed to restore regulation accuracy and tightness of gas pressure and ratio regulators of size 65. 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, especially after long-term operation at high ambient temperature. Technical specifications: Parameter Value Part numbers 74924630, 624.478.014 Manufacturer Kromschroder / Honeywell (Germany) Part type Working diaphragm Compatibility VGBF 65 /B (gas pressure regulator DN65); VAR 65 /B (differential pressure regulator); GIK 65 /B (ratio regulator) Material Perbunan (NBR) — oil and gasoline resistant rubber, resistant to natural and liquefied gas Application Natural gas, liquefied gas (propane-butane) Warranty 1 year (when purchased from official dealers) Application area and signs of wear: This membrane is used in gas pressure regulators VGBF 65 /B, differential pressure regulators VAR 65 /B, and gas-air ratio regulators GIK 65 /B. These regulators are installed on gas lines before the burner in industrial boiler houses, furnaces and heat generators to stabilize pressure or proportionally control flow. Brief information about Kromschroder regulators: VGBF — high pressure regulators with the ability to adjust output pressure in various ranges by selecting appropriate springs. GIK — ratio regulator
