Diaphragms | Special Aircraft Seals | Trelleborg

All diaphragms are custom designed to suit the requirements of an application and can either be manufactured from fabric-reinforced or thin membrane rubber-only material. Higher pressures can be accommodated, by increasing the burst resistance, with synthetic fabric reinforcement. This also gives the advantages of extended product life, reduced deformation and allows the use of thinner sections to improve sensitivity of control. Diaphragms are commonly used in aircraft fuel systems, for example in control and metering valves.
