TECHNOLOGY OVERVIEW Rotarex uses 4 main technologies to achieve a stable and reliable pressure regulation: DIAPHRAGM -- Our most-used technology (cylinder regulation, line, supply panel…) -- Compact design -- Good precision BELLOW -- High precision of outlet pressure -- Less sensitive to the pressure increase at the outlet -- Mainly used for applications like chromatography PISTON -- Stable outlet flow -- Used for regulator where the pressure outlet is close to the inlet pressure -- Used as the 1st stage for a dual stage regulator -- Used for calibration regulator BALANCED-VALVE --...

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...

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...

BODY MATERIALS Most Rotarex pressure regulators are available in stainless steel 316L or chrome plated brass, and on some models, raw brass or aluminum. Which material is best for your installation? Stainless steel 316L: The recommended option for corrosive gases and high to ultra high purity applications due to its superior resistence, nonreactivity, exceptional durability and high-surface finish properties. It is compatible with most gas types and low-velocity oxygen applications. Rotarex uses Stainless steel type 316L, an austentic chromium nickel stainless steel containing Molybdenum....
