Pop Open Pressure Relief: The divider block system is protected from overpressure conditions by the Pop Open Pressure Relief device, or POPR™ valve. This innovative device, only available from CPI, replaces the old style and unreliable rupture discs. When the divider block system over pressures, the POPR™ valve snaps open and diverts the oil to the lubricator reservoir, a closed container, lube pump oil supply line or back to the compressor frame. Unit “always” remains in open position until reset by the compressor operator. Once the system blockage has been fixed, simply reset by closing the POPR™ valve.
