Safety Valves for Heating & Cooling Series 851bH
For the protection of:
– thermostatically protected closed-circuit water heating systems with flow
temperatures of up to 120°C for all static heights or rated output above
350 kW according toTRD 721, DIN 4751 and DIN EN 12828.
Should the thermostatic limiting and control unit fail, the safety valve has to blow-off the total heating output of the boiler as hot water and steam. – Closed-circuit solar heating plants according DIN 4757-1 and 2 with flow
temperatures up to 120°C for all static heights.
– district heating sub-stations, district heating building substations and
domestic systems suitable for connection to a hot water district heating network according to DIN 4747-1 and AGFW 505.
- heating systems for building technology and industrial applications
- co-generation plants (CHP)
- biogas plants
- district heating transfer stations, building sub-stations
- solar plants
Safety valves are set and sealed at the factory.
