Pressure relief valve, DN 40 ISO-KF
- Protects vacuum systems from over pressures
- No safety component in terms of the machinery directive 2006/42/EC
- Opening pressure with nut in middle position approx. 400 hPa
- The opening pressure can vary by more than +/- 50 hPa and shows a hysteresis.
- For valves not actuated for a period of time, initial cracking pressure may be higher than the set cracking pressure.
- Please observe the maximum flow rate.
- Tightness at 1000 hPa differential pressure
- An exhaust hose can be attached to the KF connection at the outlet side
