  • Maximum Operating Pressure
    • Brass: 2,000 psi (138 bar)
    • Carbon Steel: 3,000 psi (207 bar)
    • Stainless Steel: 3,000 psi (207 bar)
  • Cracking Pressure
    • 1 to 2.5 psi (.07 to .17 bar). Other cracking pressures available. Consult factory. 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.).
