New SF07 safety valve series made of cast steel

Our new SF07 series with cast steel safety valves for set pressure of up to 40 bar, with or without a lever, joins the existing SF04 (made of stainless 1.4408) and SF06 (spheroidal graphite cast iron 5.3103) series.

Depending on the version, the safety valves are temperature-resistant up to +400°C.

Valve versions:

  • Gastight version of spring housing
  • Gastight version with bellows
  • Non-gastight, open spring housing (only for series SF06)

Important: The series SF04 and SF07 are available with DIN EN 1092-1 flanges as well as ANSI150 flanges.
