Safety Relief Valve VSBVSafety Relief Valve VSBV

  • Safety relief valve for relieving brief pressure surges in control systems preventing the safety shut-off valve JSAV from being activated unintentionally.
  • Gas types: natural gas, town gas, landfill gas, LPG (gaseous) and biologically produced methane (max. 0.02 %-by-vol. H2S)
  • Inlet pressure range up to 60 psig (4 bar)
  • Opening pressure range adjustable 8" WC to 8.0 psig / 20–500 mbar
  • Free of nonferrous metal
  • CE certified models available
  • Required for use with Regulator JSAV Overpressure Shut-off valve

Description

The safety relief valve VSBV reduces temporary pressure surges in the controlled system, especially upstream of burners, to avoid accidental actuation of the safety shut-off valve JSAV.

The safety relief valve prevents sudden pressure increases in case of gas leakages due to the gas governors not closing tightly. It is specified for gas pressure regulating plants with inlet pressures > 100 mbar, in conjunction with a JSAV acc. to the codes of practice G 491. It is suitable for air, technical combustion gas acc. to the DVGW G 260/I, biogas, and gas produced at trash plants.

The VSBV reduces temporary pressure surges caused by fluctuations in system operation downstream from the pressure reducing regulator. It is required for use with the Regulator JSAV Overpressure Shut-off Valve.
