The OMEGA PRG700 Series
regulators are designed for
applications that require high flow
capacity and accurate process
control. A poppet valve balanced
by a rolling diaphragm insures a
constant output pressure even
during wide supply pressure
variations. Stability of regulated
pressure is maintained under
varying flow conditions through
the use of an aspirator tube, which
adjusts the air supply in accordance
with the flow velocity.
