D Series Double Stage Compressed Gas Regulators

Misatu two stage regulators are recommended for applications that require a constant delivery pressure over a range of varying inlet pressures. This precise two stage regulator provides superior operating characteristics for applications where changes in delivery pressure would affect performance characteristics of work or test results.
