8601DZ05
Brooks Instrument Mechanical Pressure Regulator
About this part
Brooks Instrument 8601DZ05 is a configured identifier based on Model 8601D, the side-connection version of the 8600 Series mechanical pressure regulator. Model 8601 is a compact, direct-acting, non-relieving regulator intended for precise control in low-flow gas service. The Z05 suffix does not follow the currently published ordering-code structure, so the exact body material, diaphragm and valve-seat materials, output range, connections, and mounting options cannot be decoded from current literature. Historical and current Brooks pressure limits differ; the unit nameplate and documentation appropriate to its production era govern safe operation
Configurations vary. Verify the exact unit before choosing a replacement.

Published ordering-code boundary
The current Brooks ordering code begins with 8601D and then uses five defined option positions. The suffix Z05 does not supply those positions, and Z is not a published body-material code. Only the 8601D base-model portion can therefore be decoded conservatively.
| Position | Published codes | Meaning |
|---|---|---|
| Base model | 8601D | Pressure regulator with side connections |
| Body material | 1 or 2 | Aluminum or stainless steel |
| Diaphragm and valve-seat materials | A, B, C, or D | Published Buna-N, Viton, brass, and stainless-steel combinations |
| Output range | 1 through 5 | Current ranges from 0–10 through 0–150 psi |
| Connection | A or B | 1/8-inch or 1/4-inch NPT female |
| Accessory | A, B, or F | None, panel mounting, or plugged gauge port |
Pressure-rating revision boundary
Brooks documentation changed materially over the Model 8601 product life. The exact unit must be operated according to its nameplate and the documentation applicable to its production revision.
Model 8601 service parts
The Brooks installation and operation manual identifies the following field-replaceable filter components and installation tool. The manual discourages other field disassembly and warns against cleaning the regulator by flushing it with solvent or air.
