Aerospace Diaphragm

The diaphragm below was produced recently, our customer said,

“For a manufacturer of aerospace environmental and ecological control systems, Metflex produces a highly critical valve diaphragm manufactured from FDA compliant nitrile rubber, reinforced with their proprietary disbursed fibre technology (DFT). The fibre reinforcement ensures stability and consistent functional performance over the required range of temperature and pressure conditions, whilst providing greater sensitivity and improved sealing performance than typically possible with alternative fabric reinforced materials. The application also requires very tight dimensional tolerances, with thickness being controlled to less than the ISO 3302-1 Class M1 allowance. The diaphragm is suitable for use in aqueous environments and is unaffected by normal cleaning, disinfectant, and deodorant products. It also functions reliably after repeated freeze-thaw cycles such as may be encountered in aircraft operation.”
