Back Pressure

Back pressure may be required to reseal the valves with nominal cracking pressure of 5psi or lower

 

Example

For a valve with a spring having a rated cracking pressure of 25psig (1.72bar), the actual cracking pressure

ranges between 22 and 28psig (1.52 to 1.93bar). The re-seal pressure range would be 16 to 22 psig (1.10

to 1.52bar). Check valves having springs with rated cracking pressure of 3psig (0.21bar) or less may require

up to 4psig (0.28bar) back pressure to re-seal bubble-tight.
