K-SERIES FLOW UNLOADERS

Flow actuated unloaders are activated when the trigger of the gun is released and the flow stops. Pressure between the pump and gun is reduced to near zero pressure.

K-3 SERIES
  • This unloading valve is a flow-through design and should be mounted on the discharge line of the pump in any position (vertical or horizontal) which allows easy access to the adjusting bolt.
  • A pressure gauge should be installed on either side of the port of the unloader to accurately read pressure during adjustment.
  • Minimum 5% bypass is required for proper operation.
  • Features all stainless and brass internal parts.
  • No external moving parts or springs.
  • Unique balance principle: eliminates high pressure in all lines while unit is in bypass mode.
  • Elimiates pressure peaks normally generated by conventionally designed unloaders.
  • Dual gauge ports
