Main Applications
- Chemical industry
- Boiler feed applications
- Boiler recirculation
- Condensate transport
Technical Data
- Nominal pressure
- PN 63, PN 100
- Max. nominal size
- DN 400
- Maximum allowable fluid temperature

Benefits
- Additional features ensure safe sealing to atmosphere:
- Risk of leakage is reduced by internally mounted hinge pin. The hinge pin mounting bracket is welded directly to the inside of the cover, so no additional seal to atmosphere is required.
- Serrated cover gasket, fully confined to prevent creep.
