This analytical series of high-purity brass, two-stage regulators is recommended for non-corrosive analyticaland process applications where precise pressure control isrequired. This series is ideally suited for chromatographiccarrier gas applications including FID, TCD, ECD, HID, andnon-corrosive gas mixtures for analytical instrumentation.These units feature stainless steel diaphragms and bar stockbodies with low internal volume and minimal dead space.The check valve cylinder connection prevents air and conta-minants from entering the gas stream during cylinder changeout. This creates consistencies in processes and extendscolumn life in GC applications. The needle valve model hasthe valve built into the regulator body reducing the gas path.The two-stage design yields a delivery pressure change ofless than 0.26/100 psi inlet change, making this one of themost accurate regulators available from full cylinder toempty. An automatic reseating relief valve protects regulatorcomponents from over pressurization while the encapsulatedfilter assembly protect the valve seats and extend operatingservice life. These regulators are nickel-plated to maintaintheir appearance through years of service.
