Model DA5 Back Pressure Regulator

The Model DA5 is a high performance, spring operated, back pressure regulator with top-guided 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 design. Applied primarily in clean gaseous service, but also can be applied as a liquid or steam valve.

Application

“DO-ALL” concept allows application of all types of clean fluids. Designed primarily as a gaseous service valve, can be applied in liquid service applications where excessive cavitation or flashing is absent. Excellent for atmospheric industrial gases – GN2, GOX, Ar, He, H2, CO2 – as well asa natural gas back pressure regulator. Used as a utilities – air, oil, water, steam – back pressure regulator. Corrosive and non-corrosive chemical services – gas or liquid – are possible with broad materials range. Special variations available for cryogenic gas or liquid service.

  • Versatile: Five basic materials and multiple trim material combinations to select from.
  • Tight Shutoff: Multiple composition materials pro vide Classes II, IV or VI inboard leakage rates. Designed as a soft-seated valve.
  • Capacity: Highest in the industry. Allows smaller body sizes than competitors in majority of applications.
