Doering Company Decompression Valves

Our decompression systems use pilot operated valves as a means of achieving two stage decompression. The objective is to gradually reduce the system pressure until the threat of decompression shock no longer a factor and at that point of the pressure reduction cycle, open a second valve with greater flow capacity which will allow the cylinder or vessel to complete the drain to reservoir (tank) cycle. The relationship of decompression to pressure is complicated by cylinder or vessel diameter, length and diameter of hoses in the system. Each system may be unique and safe stage two decompression pressure should be determined based on testing by the OEM and then determining a safe PSI for each system design.
