A pressure relief valve is a device that limits the build-up of excess pressure or vacuum within a system when these parameters reach or exceed a predetermined value relative to atmospheric pressure. The suction side of the valve is weight-loaded, while the pressure side is spring-loaded. A tight seal is ensured by properly ground components (valve body and valve seat).
Weight-loaded combined breathing valve for overpressure and vacuum, with reduced opening pressures from ±1 mbar to ±4.5 mbar. Exhalation and inhalation take place into and from the external environment.
