  • 25#
  • other options are available.

Cracking Pressure:

Valve poppet is actuated when the pressure dierence between the inlet (upstream) and the outlet (downstream) reaches the range of cracking pressure.

Reseal Pressure:

Valves that have higher cracking pressure can be resealed to bubble-tight by the spring force. The reseal pressure is the pressure at the same ow direction, but lower than the cracking pressure.

Back Pressure:

Valves that have cracking pressure of 5 psig (0.34 bar) and lower may not be able to return to the bubble-tight seal. This may require back pressure to press the seal to form a bubble-tight contact in addition to the spring force.
