DO-ALL SERIES 1 PRESSURE REDUCING REGULATOR

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.

Applications: 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 available for cryogenic gas; consult factory.

Features

  • Highest capacity in the industry. Allows smaller body sizes than competitors in a majority of applications.
  • Highest in the industry when coupled with high flow capacity.
  • Basic valve gives outstanding rangeability due to close tolerances, balanced trim, and a broad range of elastomeric diaphragms and soft seats.
    Can be as high as 1000:1.
  • Multiple composition materials provide Class IV or VI inboard leakage rates. Designed as a soft-seated valve.
  • Five basic materials and multiple trim material combinations to select from.
  • "DO-ALL" trim design provides FTO and pressure balancing for higher inlet pressure. Results in unmatched sensitivity and stability.
    Internals are cage-contained within easily removable quick change trim.
  • Both top and bottom guided to maintain stability and increased diaphragm life.
