Prevco’s pressure relief valve, vacuum port adaptor (VPA) is a useful addition to our line of subsea underwater housing support equipment. It addresses an all too common problem. When vacuum leak testing an enclosure, there is often a loss of vacuum when replacing the vent plug and/or a loss of pressure when back-filling with Nitrogen. This small assembly provides a key link between our industry standard, Portable Vacuum/N2 Backfill Kit and a Prevco Dual Seal DUAL POPPET Pressure Relief Valve. This ensures that a housing can be sealed with an internal vacuum and that any back-filling gas is not mixed with atmospheric air when the PRV or vent plug is replaced. The pressure relief valve, DUAL POPPET vacuum adaptor, addresses this by allowing both procedures to be performed through the Hi-Pressure, DUAL POPPET pressure relief valve. The adaptor, temporarily mounts onto the PRV and physically opens the PRV poppet while the vacuum is being pulled. The poppet remains open while backfilling with Nitrogen and then closes after use, minimising the possibility of losing first vacuum and then pressure.
