Positive Pressure Clean Room

SKB Flow's facility includes a dedicated Positive Pressure Clean Room for the assembly and testing of valves and valve-related products destined for oxygen duty, cryogenic, and other critical-process applications — preventing contamination at every stage.

Step 01
Solvent & aqueous cleaning
Both solvent-based and aqueous cleaning processes available to meet specific customer and service requirements.
Step 02
Cleanliness verification
Direct visual inspection using white and black light techniques, plus sample wipe and solvent analysis procedures.
Step 03
Final assembly
Post-cleaning assembly performed within the clean room environment to maintain integrity throughout the process.
Step 04
Sealing & labelling
Parts are sealed, bagged, and labelled upon completion to prevent contamination during transport and storage.
