      Hey there,

      I came across a slight dilemma. I have a pressurized vessel with about 120 Bar (roughly 1740.45 psi) I need some type of system and/or valve, that could help me take the internal pressure from 120 bar to atmospheric pressure in 6 minutes with a constant flow rate of about 20 bar per minute. Any suggestions? or possible experience on this subject? Would also need to record the flow rate... Thanks in advance.

      |Hi Gbahena

      I assume your talking about an oil hydraulic system, how are you raising the pressure to 120 Bar?

      Depending on the rest of the system, you could use either a proportional pressure relief valve or a proportional pressure reducing valve.

      The rate of drop in pressure would be controlled electronically, using a pressure transducer as feedback, this could also be used to record the change in pressure.
