  • Maximum Operating Pressure
    • Brass: 60 psi (4 bar)
  • Cracking Pressure
    • 1 to 2.5 psi (.07 to .17 bar). Soft seat check valves if left seated for a period of time, will have the rubber adhere to the metal it is in contact with. This results in an initial high crack point due to sticking. The degree depends on many things (time seated, pressure, etc.).
