Advanced Specialty Gas Equipment introduces its new ultra low delivery pressure, two-stage bar stock body, metal diaphragm regulators. These high-purity regulators feature a large 2-¾†diameter stainless steel diaphragm providing very sensitive pressure control as low as 0.2 psig up to a maximum of 2 psig. The two-stage design provides constant outlet pressure regardless of changes in cylinder (inlet) pressures. They are available in chrome-plated brass or Type 316SS construction and are ideal for low-pressure control of pure, inert and mildly corrosive gases used with calibration and other analyser processes.
“Many applications requiring such low pressures must use two regulators to reduce the pressure to this low setting,†states Fred Marencik, Product Manager. “Most low delivery pressure regulators available in the market cannot be used directly on high pressure (up to 3000 psig) cylinders and cannot accurately maintain the pressure setting throughout the life of the cylinder. Often, a regulator has an elastomeric diaphragm that can absorb and emit contaminates into the gas stream unpredictablyâ€. The Models THP and THPS regulators are constructed with all stainless steel diaphragms and are specially cleaned for high precision calibration service.
