Avoid a wrong match
- An additional L suffix is not listed in the PSL ordering code.
- PSL tube/thread pairs differ from PSS.
- Follow source controlled/free flow arrows and A/B marking.
- Closed-state leakage allowed; not a zero-leak shutoff.

Helpful for Model Matching:
| Identity and legacy route | PSL is the elbow speed controller in the current ordering code; an additional L suffix is not listed. PSA inline, PSS universal and PSL-S stainless are separate; their pairing and material data do not apply to PSL. |
| Valid tube/thread pairings | Tube OD4: M5/01; OD6: M5/01/02/03; OD8:01/02/03/04; OD10:02/03/04; OD12:03/04. M5=M5×0.8;01/02/03/04=PT1/8,1/4,3/8,1/2. This PSL matrix differs from PSS. |
| A/B controlled and free flow | Source A meter-out: controlled from threaded end to tube; free from tube to threaded end. Source B meter-in: controlled from tube to threaded end; free from threaded end to tube. Match the actual source arrow, handle A/B marking and machine connection; the name alone does not identify the flow direction. |
| Colour and suffix | Blank grey release button/body, D black. Published pipe-thread type blank=PT; M5 remains metric. No G/T, S stainless or final-L option is published for this PSL code. |
| Pressure, temperature and tube | Operating0–1 MPa, proof1.5 MPa separately, negative pressure−750 mmHg (10Torr in source), ambient/fluid−20 to70°C. Applicable tubing soft nylon or polyurethane. Confirm actual tube tolerances, fluid and installation; no universal fitting/media approval. |
| Body and dimensions | Source describes nickel-plated brass body and anti-drop regulating rod; own PSL dimensions use tube OD, thread, Cmax/Cmin, EA/EB and wrench flats. Example PSL401: L7.5,C41.5/35,EA20.5,EB15,H11mm. Do not transpose PSS dimensions or describe the complete assembly as stainless. |
| Installation and initial adjustment | Insert tube to its stop; release only after zero pressure. Mount with wrench and confirm fitting torque/screw-in depth. Start adjustment from fully closed and open slowly; sudden pressurization with the valve open may cause rapid cylinder motion. Clockwise reduces flow, counterclockwise increases it. |
| Not a shutoff or safety approval | A certain amount of closed-state leakage is allowed; source explicitly says it is not a zero-leak stop valve. Do not turn the handle with pliers or force the end stops. Flow curves are size-specific and controlled-flow examples refer to0.5 MPa; actual actuator dynamics remain to be confirmed. |

The current PSL code lists OD, thread, A/B direction and optional D color; an additional L suffix is not listed. Send any label with a different suffix for confirmation instead of assuming it matches.
