Rapid drain valve

Petrometalic has developed rapid drain valve technology:  a relief valve considerably reduces the time it takes to drain flexible hoses and inflatable packers during injection or drilling operations, particularly at great depths.


For dry drilling:

  • Command:  Air: 6/7 bar – water: 30 bar
  • Safe: installed directly on the head of the inflatable packer (no Rilsan bond)
  • Stop valve:  brass, 400 bar
  • Pilot head:  stainless steel, 100 bar
