Remarks
  1. PNB is actuated pneumatically by a solenoid valve to discharge oil intermittently. The pneumatic pressure supply controls the output pressure of PNB.
  2. PNB requires 4-8 kgf/cm2 pneumatic pressure supply and 5 seconds above ON/OFF time of the solenoid valve to work functionally.
  3. PNB has to work with volume distributors to deliver the metered quantity of oil to the lubrication points.
  4. PNB has a pressure gauge that enables the user to check the operating pressure easily.
  5. PNB has a NC contact float switch that detects the oil level automatically and sends signals when the oil level is low.
  6. An 8kgf/cm2 socket pressure switch can be added to PNB on request to detect the operating pressure automatically.
  7. A magnetic filter and a partition can be added to PNB on request to filter the oil that returns to the oil tank through the cyclic inlet.
    ● 3L oil tank and above can add a magnetic filter.
    ● 3L, 4L resin oil tanks, and 8L iron oil tanks can add a partition.
