Kunkle Bailey 616d Safety Valve

A spring operated high capacity safety valve for low-pressure air applications


  • Designed to deliver precise relieving and re-seating pressures.
  • Protected open discharge gives downward flow
  • Non-stick seating surfaces give positive shut-off and freedom from sticking.
  • Mixture of aluminum and gunmetal creates a light but very robust construction.

General Application

typically used on blowers or bulk transfer road/ rail transport vehicles, the 616D is specially designed to give overpressure protection of positive displacement air blowers and associated tanks or pressure vessels.
