The DN 16 ISO-KF valves are pressure relief valves for use in pumps and small to mid-range vacuum systems. They serve the purpose to prevent the build-up of overpressures >1150 mbar. Technical details on the relevant opening pressures and serial numbers are printed onto the valve.
The valve opens at pressures above 1150 ±40 mbar. If the pressure inside the vacuum system is below 1150 mbar, the valve remains closed.
