AirTAC PSA ordering official English reference
Helpful for Model Matching:
| Identity and pneumatic direction | 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. |
| Ordering and interface | 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. |
| Operating and tubing conditions | 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. |
| Material scope | Shared structure table and numbered PSA drawing identify aluminum-alloy adjusting/locking caps, brass throttling column/body, NBR seals, PBT holder/plastic bodies, POM locating seat/interface, stainless spring gasket and aluminum-alloy locating ring. This is a mixed-material assembly, not all-metal, all-brass or stainless. |
| Own installation envelope | 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. |
| Closed-state and operation boundaries | Catalogue operation section expressly allows some leakage in the closed state and says the speed controller is not a stop valve with zero air leakage. Do not use it as shutoff, safety, emergency-stop or safe-load valve. Release tubing only after line pressure reaches zero. Avoid pliers/excessive adjustment force; confirm controlled adjustment and circuit behavior. |
| RFQ inputs | Send exact PSA code or label, tube OD/material/hardness, gray/black body/button requirement, actual inline direction/circuit photo, pressure/vacuum/temperature/fluid, desired flow/speed behavior, mounting and adjustment space, quantity and destination. Application fit and availability are inquiry confirmations. |

No. PSA uses tube OD and optional D color only; threaded-port/A-B fields belong to other forms. The catalogue permits closed-state leakage and excludes zero-leak stop-valve duty. Send original code, actual direction and circuit for confirmation.
