Three-port, chrome-plated brass barstock, point-of-use regulator for high purity inert gas applications
The CONCOA 304 Series single stage, pressure reducing regulator decreases delivery pressure in one step. They are intended for secondary pressure control of non-corrosive, liquefied, or high purity (up to grade 5.5) gases or as point-of-use pressure control in high purity gas distribution systems. With features like high purity compatibility and durable construction, CONCOA 300 Series single stage regulators are a cost-effective option for final line regulation in applications that can tolerate fluctuations in outlet pressure due to diminishing inlet supply. Like almost all CONCOA regulators, the maximum inlet pressure for the CONCOA 304 Series regulator is at least 3000 PSIG (210 BAR) or more, depending on the configuration.
