STRATE BEV-G for coarse ventilation

Area of use

The BEV-G is a single-stage valve offering only the function of the first ventilation stage (coarse ventilation) provided by the two-stage valve (BEV-GF).

It is not necessary to coordinate the valve to the working pressure in the first ventilation stage, since coarse ventilation is always closed under pressure.

Product features

  • Type G (coarse ventilation): The air escapes through this valve until the medium closes it as it continues to flow. The valve remains closed under operating pressure.
  • Ventilation of individual sections in sloped pressure lines, especially as a low pressure safety feature
  • Quick ventilation of high points if fine ventilation is not required (short pump run times)
