MODEL DA5
DO-ALL SERIES V
BACK PRESSURE
REGULATOR Spring Operated: 1/2" – 4" (DN15 - 100)
The Model DA5 is a high performance, spring operated, back
pressure regulator with top-guided piston-cylinder that pro vides 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 pi lot-operated de signs in the basic design.
Applied primarily in clean gaseous service, but also can be applied as a liquid
or steam valve.
APPLICATIONS
“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 as a 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.
