In many system applications there are functions that require reduced pressure (prefill, exhaust, etc.). BOC's Pressure Reducing Orifice Stacks allow you to control flow and reduce pressure to your exact needs.

The multi-stage pressure drops are created by the tortuous flow plates, alternating flow across a single hole, then a four hole pattern. Our Orifice Stacks are extremely field friendly. Plates can be added or removed in minutes to adjust flow or pressure drop characteristics.

  • Available in stacked plate or threaded disk form
  • Extra studs supplied for additional plates
  • Capable of raw water operating up to 5000 psi
  • Repeatable flow characteristics, without variation
  • High quality materials
  • Rugged construction
