Series PRD is a differential pressure regulator based on Series PR with two threaded ports. One port is for a downstream pressure sensing line, the other is fitted with a bleed screw to exhaust air from the housing. Otherwise, design is identical to Series PR. The sensing line feeds the pressure downstream (P3) of the equipment being protected to the top of the spring housing (also P3). This pressure assists the spring in keeping the regulator open against the pressure directly at the regulator outlet (P2). When pressure downstream begins to drop (as it would when a filter becomes more and more clogged), the regulator begins to close and becomes fully closed when the differential setting is reached. This assures against overpressure across the bank of filters or whatever the equipment may be. The differential pressure setting is P2 minus P3.

  • Pressure setting is infinitely adjustable from 5 psi to 50 psi.
  • Maximum inlet pressure is 150 psi.
  • Available in Grade 1, Type 1 Geon® PVC
  • Sizes 1/4", 1/2", 3/4", 1", 1-1/2", 2" & 3".
  • Installs easily; common tubing is used to connect to desired point downstream.
  • Spring is fluoropolymer coated since downstream liquid is in contact.
  • Seals in EPDM or Viton.
  • High performance, heavy-duty design.
