Fisher 627-496 627 Series direct-operated pressure regulator - Application, Fit and Verification
A practical guide to choosing the right configuration
The model shown here identifies a specific family or listed configuration. The page intentionally avoids decoding unverified suffix characters: those can represent options that affect performance, installation or compliance. Use the table as a concise identification aid, not as a substitute for a complete datasheet review. The 627 family includes direct-operated pressure regulators for a range of systems. Do not infer spring range, body size, connection, outlet pressure or relief features from the abbreviated code; confirm nameplate and application data.
For a new installation, define the measurement or control objective and the limits that matter to the process. For a replacement, compare the current device and proposed 627-496 against the installed wiring, connection, range, materials and configuration. A family-level match is not by itself proof of interchangeability.
Details for a replacement inquiry
- Photograph the complete nameplate and transcribe every suffix without normalization.
- Record the process, electrical or pneumatic conditions and the connected equipment model.
- Confirm mounting, connections, materials, output/interface and required approvals.
- State quantity, destination, documentation and delivery expectations.
Operating conditions and fit
Evaluate the device under the actual process conditions and against the installed system interface. Confirm normal and upset conditions, connection dimensions, materials, signal requirements, supply utilities and any site-specific hazardous-area or functional-safety constraints. Pressure reduction for utility and process systems should be assessed as part of the complete loop or assembly, not as an isolated part number.

The 627 family includes direct-operated pressure regulators for a range of systems. Do not infer spring range, body size, connection, outlet pressure or relief features from the abbreviated code; confirm nameplate and application data. Keep the exact model 627-496 on the purchase request and ask the supplier to confirm the full build before order acceptance. This is especially important when a legacy code, regional option or safety-related application is involved.
