  • With shut-off and venting function
  • Incl. lead sealing kit
  • Proofed Barrier (odour-tight)
  • Materials resistant to biofuel and biodiesel mixtures with max. 30 % FAME
  • Watertight up to 10 m water column - ideal for use in flood hazard areas

Application

For oil carrying suction pipes in oil consuming systems where a pipe section is below the maximum tank level. MAV keeps fuel oil from being siphoned out of the tank in the case of leaks.

MAV is continuously adjustable to a safe height of 1–4 m for optimum adaptation to suit local conditions. The adjusted value corresponds to difference between the installation height and the lowest point of the oil line. MAV shuts off under spring pressure and opens under the vacuum caused by the pump. Watertight up to 10 m water column. If necessary, install a pressure compensation unit.
