GR nine body/port combinations, adjustment range, inlet pressure, temperature and weights

Helpful for Model Matching:

  • Full model or installed label; quantity and destination
  • Published body/port pair and PT/G/NPT thread
  • Standard or L low-pressure adjustment; inlet pressure separately
  • With bracket or J without bracket (standard configuration)
  • F square / C round gauge and scale, or N without gauge
  • K reverse-flow valve requirement and IN/OUT direction
  • Installation dimensions; no filter or drain option applies
  • Use the GR installation dimensions for the exact body and port; GFR bowl drawings describe a different assembly.
  • Compare gauge mounting, bracket configuration and IN/OUT direction
  • Use GR flow curves at the printed 0.7 MPa inlet condition; no single rated-flow claim

About GR

GR provides pressure regulation without filtration, a water bowl or lubrication. Nine published body/port combinations cover GR200/300/400/600. Adjustment is 0.05–0.9 MPa; L limits maximum adjustment to 0.4 MPa. Maximum inlet pressure is separately rated at 1.0 MPa. J without bracket is marked as the standard configuration; the blank field includes a bracket. Compare gauge shape and scale, reverse-flow requirement and the exact installation drawing for replacement work.

Matching Questions

Can GR200-08 and GR300-08 replace each other because both have 1/4 ports?

A shared main port does not establish fit. GR200 has an 89 mm reference height and 160 g weight; GR300 has 112.5 mm and 350 g. Compare pressure range, gauge, reverse-flow option, bracket and installation dimensions using the installed label and photo.

Does GR include filtration and a drain like GFR?

GR is a pressure regulator only. It has no filter element, water bowl or drain-code field. GFR combines filtration and pressure regulation. A matching port size alone does not make GR and GFR interchangeable.
