DA1-1"-55-BRZ/BRZ/M7/30-150psi, O2-clean
The Model DA1 is a high performance, spring operated, flow to-open, pressure reducing regulator with internal pressure
balanCing piston-cylinder that provides high flow capaCIty and high pressure drop capability. Internal trim design allows the
same basic unit to cover a broad range of pressure settings. Performance approaches that of competitive pilot-opeRated
designs in the basic construction. Applied primarily in clean gaseous or liquid services. Truly a “DO-ALL” pressure
regulator.
The “DO-ALL” design allows application of all types of clean fluids. Designed primarily for gaseous and liquid service applications where excessive cavitation is absent. Excellent for atmospheric industrial gases – GN2 , GOX, Ar, He, H2 , CO2 – as well as a natural gas regulator. Used as a utilities – air, oil, water, steam – regulator. Corrosive and non-corrosive chemical services – gas or liquid – are possible with broad materials range. Special variations avail able for cryogenic gas;
