GF PVC Ventilating & Bleed Valve Type 591

These valves are primarily used where containers and pipes have to be aerated and/or vented. The float in the type 591 opens the valve if the level of the liquid falls. If the level of the liquid rises, the float is raised and pressed against a seal. The valve is then closed. Ventilating and bleed valves are mainly used for de-aerating of air, while filling piping systems and tanks, avoiding vacuum and discharging air pockets.

  • PVC
  • FPM or EPDM seals
  • Valves supplied with threaded & socket end connectors
  • Installed vertically with the arrow pointing "up"
  • Valve can be positioned at absolute & temporary high points, after pumps or at turning points
