- Maximum Operating Pressure (non-Shock Service)
- Brass: 2,000 psi (138 bar)
- Carbon Steel: 5,000 psi (345 bar)
- Stainless Steel: 5,000 psi (345 bar)
- Maximum Operating Pressure (Poppet Check)
- Brass & Stainless Steel: 60 psi (4 bar)
- Cracking Pressure
- 1 to 2.5 psi (.07 to .17 bar). Soft seat poppet 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.).
