Weight Reference
Catalog reference weight: 1700 g for the GR600 body family. The catalog does not assign a separate weight to every gauge, bracket, drain or thread option. Actual weight is subject to the supplied product; this is not an individual weighing or a packed shipping weight.
Included Configuration and Compatible Connections
Parameter
Details
Supplied functional product
Pressure regulator. This listing does not include a separate lubricator or a multi-unit air-preparation set.
Pressure gauge
Not supplied for this N configuration; a gauge in the drawing is a dimensional reference.
Mounting bracket
Supplied under the blank bracket option.
Replacement bowl, filter and service parts
Use parts explicitly selected for this body family, size, bowl material and drain type. The construction numbers identify internal parts; they do not establish standalone ordering codes, service-kit contents or package quantities.
Application connection
Match the inlet and outlet thread standard and nominal size to the pneumatic circuit. The catalog does not restrict this air-preparation product to one named directional-valve or cylinder family.

Dimensions and Mounting
Drawing dimensions are in millimeters unless a thread or another unit is stated. Each local callout retains its original view and datum; separate values must not be added to create an unpublished overall size. Gauge and bracket geometry is shown only as reference when those items are omitted by the current code.

Pressure and Flow Characteristics
Parameter
Details
Applicable graph
GR600
Flow graph
Flow in L/min versus secondary/outlet pressure in MPa; printed flow labels extend through 15000 L/min and pressure labels through 0.6 MPa.
Flow-graph condition
Inlet pressure 0.7 MPa
Pressure-characteristic graph
Inlet-pressure scale 0–1.0 MPa; secondary-pressure scale 0.18–0.22 MPa, around the illustrated 0.20 MPa setting.
Reading the curves
The graph axes and endpoints are plotting references, not rated flow claims. Read the actual curve at the required operating condition in the PDF.
Other Series Ordering Choices
These are catalog alternatives. They do not change the selected configuration identified above and are not additional supplied parts.
Parameter
Details
Body and port choices
200: 1/8 and 1/4 inch; 300: 1/4, 3/8 and 1/2 inch; 400: 3/8 and 1/2 inch; 600: 3/4 and 1 inch.
Thread choices
Blank: PT; G: G thread; T: NPT.
Gauge options
Blank supply code includes a gauge; N omits it. F specifies square and C circular; scales 1/2/3 specify MPa/psi/bar.
Reverse-flow option
Blank omits the reverse-flow valve; K includes it.
Pressure type
Standard: maximum adjustable pressure 0.9 MPa; L: maximum 0.4 MPa. The lower limit depends on the current product and drain arrangement.
Bracket supply
J means no bracket; blank means bracket supplied.
Installation and Catalog Notes
The push-in lock is part of the pressure-adjustment mechanism; lock the setting after adjustment. The plotted regulation characteristic is shown around the catalog setpoint and does not replace the selected pressure-range limit.
Select fittings, gauges and replacement parts for the stated version and interfaces. A matching nominal port size alone does not establish interchangeability with a different body series or catalog edition.
