| PSA4/6/8/10/12 denotes tube OD4/6/8/10/12 mm. Blank gray or D black applies to release button and body. No thread-size/PT/G/T/M5 field, unequal tube pair, inch port, A/B field or stainless-S option is established in PSA ordering. | PSA is a straight inline tube-to-tube speed controller with its own one-way throttling/check symbol. Both connections are push-in tubing ports, not threaded cylinder elbows like PSL/PSS. Confirm installed orientation against the symbol, device markings and actual circuit. No A/B meter-in/out ordering field is published for PSA; do not inherit the threaded PSL/PSS direction selector. Operating0–1.0 MPa; proof1.5 MPa separately; ambient/fluid−20 to70°C. Applicable soft nylon or polyurethane tubing. Source negative-pressure notation−750 mmHg(10 Torr) is retained as notation, not signed-unit equivalence. Actual tubing rating, fitting material/hardness/OD sealing and fluid compatibility require confirmation, not universal water/oil/chemical approval. | For OD4/6/8/10/12: total A41/52.5/59.5/69/78.5 mm; width B11/16.5/16.5/21/26 mm; adjustable height C max29/43.5/47/53.5/58.5, min26.5/36.5/40/46.5/51 mm. Mounting holes ØJ3.2 mm for4 and4.3 mm for6–12. Weights7.85/18.3/23.5/42.4/67.5 g. These are own PSA dimensions, not PSL/PSS elbow wrench values. Own PSA controlled-flow-versus-turns and free-flow-versus-inlet-pressure charts cover all five tube sizes. Controlled PSA chart boxes do not print the0.5 MPa condition shown in neighboring PSL/PSS charts; do not transfer it silently. Retain curves as reference and confirm actual conditions. No constant flow, linear turns law, guaranteed cylinder speed or universal direction inferred. |
