The safety valves 6HL (7HL) are poppet-type pneumatic valves. They have a valve part and a control part in a housing. The valve part has a cap with a filter, a diaphragm, a pedestal and a bellmouth. The control part has a position switch, a negative delta-P check-valve and a controller. The position switch is connected electrically to the System Data Aquisition Concentrators (SDACs). The negative delta-P check-valve opens if the external pressure is higher than the internal pressure. The controller has a diaphragm, a poppet and springs to preload the poppet. The poppet gives accurate limit control. If the internal pressure is more than the design goal of 8.6 psi (0.5929 bar) above the external pressure, the poppet moves and air flows out of the fuselage. For negative delta-P condition it is ensured by a minimum of one safety valve operating, that the internal pressure is not more than 0.175 psi (0.0121 bar) below the external pressure.
