Pressure Relief Valve
Regulator
Pressure Regulator
During a test, the computer will be continuously adjusting the pressure inside
the cell. As the pressure increases due to thermal expansion, the computer
will allow pressure to bleed. Likewise, if pressure begins to drop, the
computer will add pressure to keep it within the target range.
There is a secondary Regulator (#120-50-037) which controls the air
pressure to the pressure relief valve.
This regulator comes calibrated and requires no adjustment unless a part
within this system has been replaced.
If the user must gain access to the regulator, simply remove the stainless
steel drip tray (#120-35-015) on top of the cabinet. The regulator and
gauge will be located underneath the tray. To set the regulator to the proper
pressure, apply pressure to the system and begin opening the regulator
between 40 – 50 PSI (276 – 345 kPa). If the pressure relief valve does not
open, continue adjusting the regulator to a higher pressure as needed to
obtain optimal operation of the relief valve.
