Description

Details

Model 621 Discharge Unloader Valve will divert the total output of the air compressor to the atmosphere, while the check valve prevents back flow from the air receiver. With the compressor producing air at just above atmospheric pressure, the motor or engine horsepower draw is greatly reduced and also has a cooling effect on the compressor.

Detail Features:

  • Brass Construction, ASTM B16.
  • Every safety valve is set and tested at the factory.
  • Heavy duty construction for lasting performance.
  • Top quality design, engineering and precision manufacturing.
  • Precision machined for smooth operation.
  • Stainless steel spring.
  • Tested in National Board Approved Quality Assurance Process.
