451bHF Safety valves with bellows made of stainless steel
Universal high-quality safety valve made of extremely corrosion-resistant stainless steel with stainless steel bellows, designed to meet the highest requirements.
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.
For the protection of:
- Combined heating and cooling systems
- Cooling and/or heating circuits and heat exchanger of cogeneration plants (CHP)
- Cooling systems and closed cooling circuits
- Thermostatically protected water heating systems with a closed circuit with supply temperatures up to 120 °C for all static heights or nominal power above 350 kW.
- Heating and cooling installations in construction and industrial engineering
- Cogeneration plants (CHP)
- Cooling and refrigeration technology
Safety valves are set and sealed at the factory.
