  • Maximum operating pressure 80bar
  • Nominal bore (free cross section) of valve 4mm
  • Nominal bore of piercing needle 2mm
  • No destruction of thermo bulb by combination of several control methods
  • No tool required for tensioning piercing needle and thermo bulb
  • Ambient temperature range: -25°C to +110°C
  • CO2 bottle and thermo bulbs are not included in our supply
  • Drawings see data sheet TAVZ2.x
  • Design of the SHEVS may require reliable venting of the piping. 

Types:
