The 492 Series cylinder regulator provides primary pressure control of non-corrosive gases in high purity applications requiring ultra-high pressure. Rather than a diaphragm, the 492 Series regulator uses a robust piston assembly to ensure safe pressure control at high inlet pressures. The CONCOA 492 Series regulator is available with a variety of options installed at the factory. The regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
