The purpose of a Plunger Style Drain Valve is to fill the Nozzle or Stud Pad with the
plunger/extended body so that there is no dead space to fill with product. This can be a great assist in solving plugging
or mix ratio issues. The Tretter Plunger Seal and Body Seal provide for a high seal quality in a wide range of configurations.
