429 Series Regulator

Four-port, stainless steel barstock, single stage regulator with face seal connections
4294411-01-001 shown

The 429 Series single stage regulator is intended for primary pressure control of the highest purity gases or other applications that require face seal connections. They are ideal for applications that can tolerate minor fluctuations in outlet pressure or applications where periodic readjustment of delivery pressure does not present a problem. Like almost all CONCOA regulators, the maximum inlet pressure for the CONCOA 429 Series regulator is at least 3000 PSIG (210 BAR) or more, depending on system configuration.
