HOKE's 7 Series Fire Safe Valves meet demanding application requirements in the production environment of chemical and petrochemical processing facilities. These valves have been tested to and meet the requirements of API 607,4th edition for soft- seated valves. API 607 measures the ability of a closed soft-seated ball valve to retard the propagation of a fire (downstream and to atmosphere). The 7 Series Fire Safe Valves offer high flow, safety, and flexibility in a variety of end connections and sizes. This series is available in fractional sizes from 1/2"to 1"and in metric sizes from 12mm to 25mm in tube and pipe ends.

Typical Applications
  • Chemical processing
  • Petroleum refining
  • Gas distribution
  • Hydraulic fluids
