Danfoss 009G0191 BML 22s shut-off valve: connection size, pressure and refrigerant checks
Danfoss 009G0191 is a BML 22s handwheel-operated diaphragm shut-off valve for refrigeration service. The manufacturer lists 22 mm (7/8 in) ODF solder connections, a brass body and a 28 bar maximum working pressure for this order number. The shared climate-solutions collage represents the product category, not the exact 009G0191 valve.

Define the valve duty
Danfoss 009G0191 is a manually operated shut-off component, not a solenoid coil or electronic control valve. Check whether the installed valve is used for isolation, service or a particular line arrangement. A visually similar 009G or 009L number can have a different connection size or product role.
Connection and pressure review
Compare the existing copper tube outer diameter with the 22 mm ODF connection shown for 009G0191. Check the site's design pressure, valve orientation, upstream and downstream access, and any required brazing or soldering procedure. The manufacturer lists 28 bar maximum working pressure, but the complete application still needs a system-level assessment.
Refrigerant and maintenance checks
Match the intended refrigerant and service temperature to the manufacturer's current 009G0191 data. Isolate the refrigerant circuit, recover or contain refrigerant according to site procedure, and verify zero pressure before removing a valve. Inspect the body, handwheel and connection joints after fitting.
Handover and ordering
After installation, test the 009G0191 connection joints and check valve operation under the approved commissioning plan. Retain the full Danfoss order number in the maintenance record. If a supplier suggests another BML/BMT code, request a comparison of connection dimensions, pressure rating and refrigerant suitability.
Similar-looking Danfoss order references
The nearby 009-prefixed entries are similar-looking refrigeration order strings, not an interchangeability list. Check each valve or accessory identity before substituting it for 009G0191.
Final order and receiving review
For Danfoss 009G0191, provide the full printed model, application duty, electrical or process interface, and current site documentation when requesting a quote. Do not approve a similar-looking number as a drop-in replacement without checking its own manufacturer data.
On receipt, inspect the Danfoss 009G0191 label and physical interfaces against the agreed order. Record condition, supplied accessories and the commissioning result so later maintenance enquiries can use the complete identity.
