Brunnen SH0851bH

High performance safety valve with bellows, made of high quality, corrosion-resistant gunmetal. Heating systems with set pressures other than 2,5 or 3 bar are required to be protected by such safety valves. Apart from indirectly heated plants, the sizing of the valves is based on the heating output of the boiler.

connection types

• Internal pipe thread
• Male thread

Application

• CHP units (combined heat and power plants)
• biogas plants
• District heating transfer stations/ house stations
• Solar systems

• closed, thermostatically protected water heating systems

In the event of failure of the thermostatic control and limiting devices, the safety valve must blow off the entire heating output of the boiler in the form of hot water and steam. the entire heating output of the boiler in the form of hot water and steam.

• Closed solar heating systems according to DIN 4757-1 and 2 with flow temperatures up to 120°C for all static heights.
• District heating substations, house substations and house systems for connection to heating water district heating networks to DIN 4747-1 and AGFW 505.

Safety valves are permanently set and sealed at the factory.
