Sensitive, extra long-life metal diaphragm ensures gas purity and integrity. User-friendly model number enables the specifier to select optional gauges, relief and shut-off valves, and cylinder connections as part of the regulator assembly. Applications • Laboratory and Point-of-Use Gas Systems in medical, pharmaceutical, food and beverage, and other high purity applications • Process analyzer gases, metal fabrication and specialty and industrial gas cylinders Features and Benefits • Cartridge valve design incorporates a 10 micron filter that protects the regulator seat and makes service simple • Optional neoprene diaphragm provides exceptional sensitivity for precise pressure control NOTE: When choosing a regulator and control pressure, decaying inlet characteristic must be considered when the supply pressure is expected to change. The decaying inlet characteristic of a pressure reducing regulator is commonly known as the increase in control pressure due to the decrease in supply pressure. It is important to make sure this effect does not cause the control pressure to exceed the pressure rating of the unit's outlet or that of the downstream system.
