455bHL Safety valves with bellows made of stainless steel
Where the highest material and quality standards are important, spring-loaded safety valves made of stainless steel with flange connections can be an option.
This type of safety valve is also designed for the protection of large heating installations in shipbuilding and in building technical applications, serving as a necessary addition to the extensive range of Goetze products.
This pressure relief valve is for the protection of:
- Thermostatically protected closed water heating systems with supply temperatures up to 120 °C for all static heights or nominal power above 350 kW according to TRD 721, DIN 4751, and DIN EN 12828.
- If the thermostatic limitation and control unit fail, the safety valve must release the total heating power of the boiler in the form of hot water and steam.
Since these valves are entirely made of metal, they can also be installed at high ambient or radiation temperatures.
Safety valves are factory-set and sealed.
