These both KF25 & KF40 Flange Adapters are available in Aluminum and St. Steel versions. The Set Pressure can be from 0.5 psig to 7.0 psig max. with an accuracy of ± 5% of set point and reseat at around 90% of Cracking Pressure. The main applications are –
- for overpressure protection of vacuum vessels & systems
- low-pressure gas systems and cryogenic boil off of set point.
The main advantages are:
- Coupling and removal of the valve into the process line is made more convenient as there are quick-release flange connections at both ends.
- The outlet housing flange reduces the fugitive emissions of process gas when the relief valve opens by providing a piped outlet for disposal or recirculation of the process gas.
