851bHF Safety valves made of gunmetal
?
Universal high-quality safety valve made of bronze with a bronze bellows, designed to meet the highest standards. Suitable and approved for heating installations and cooling systems. The sizing of the valve is based on the heating capacity of the boiler. For indirectly heated heating units and closed cooling circuits, this is based on the flow rate of the expansion water.
Pressure relief valve for the protection of:
- Combined heating/cooling systems
- Cooling and/or heating circuits and heat exchangers of cogeneration plants (CHP)
- Cooling systems and closed cooling circuits
As well as:
- Thermostatically protected water heating systems with closed circuits with supply temperatures up to 120 °C for all static heights or nominal power above 350 kW.
- Heating and cooling systems in building and industrial engineering
- Cogeneration plants (CHP)
- Cooling and refrigeration technology
Safety valves are factory-set and sealed.
