Kepner Products Co.

Fixed Orifice Flow Controls provide free flow in one direction and Restricted (metered) flow in the reverse direction. They are standard Kep-O-seal® or Kepsel® check valves, equipped with a calibrated orifice drilled through the valve poppet nose. Kepner's bubble-tight Flexible Seal Seat™ ensures that the reverse flow is precisely controlled by confining it to the calibrated orifice. Such valves are often used in charging lines for cylinders, containers, or accumulators where it is desired to rapidly charge and then bleed back the charged fluid at a pre-determined rate. These valves handle many other applications.
