TECHNOLOGY OVERVIEW (continued) DUAL STAGE REGULATORS A dual stage regulator is basically two single stage regulators in a single body. This dual configuration provides superior pressure and flow stability vs. single stage regulators. remains constant, thereby insuring a constant outlet pressure to the application regardless of cylinder pressure. This technology avoids having to frequently adjust the outlet pressure as the cylinder pressure drops. The first stage is preset to an intermediate pressure. This intermediate pressure acts as the inlet pressure to the second stage, which is adjustable....

TECHNOLOGY OVERVIEW (continued) BALANCED-VALVE TECHNOLOGY Balanced-Valve (BV-technology) regulator gives best-of-class pressure stability due to its proprietary design of components in the high pressure zone. It is able to balance the internal forces within the regulator and virtually eliminate the effects of decreasing inlet pressure on the outlet pressure. This means that the regulator balances and compensates for any pressure fluctuation on the inlet and provides a constant outlet pressure like a dual stage regulator. This regulator type also functions as a LINE REGULATOR for a 2nd regulation...
