LESER safety valves for Heating Air Conditioning

Safety valve requirements for heating and air conditioning systems.

The TRD 721 is the governing standard for the heating and air conditioning industry. In sections 5 and 6 the specific requirements for safety valve design are established:

  • TRD-721 section 6 for water heating plants up to 120° C with soft seal discs and elastomer bellows.
  • TRD 721 section 5 for steam producers up to 1 bar overpressure with metallic sealing disc and elastomer bellows.

Because of extensive product standardization, short delivery times are common.
