Helpful for Model Matching:
| PSS identity | PSS universal one-way speed controller with tube-to-thread interfaces and360° adjustable tube insertion orientation. It is distinct from inline PSA and elbow PSL. Universal describes orientation, not compatibility with every tube/thread, bidirectional equal regulation or swivel service life. |
| A and B controlled direction | A meter-out: controlled threaded end→tube, free tube→thread. B meter-in: controlled tube→thread, free thread→tube. Use actual actuator circuit and A/B handle marking; do not reverse meanings from mounting appearance. |
| Published interface matrix | PSS4M5, PSS601, PSS602, PSS801, PSS802, PSS1002, PSS1003, PSS1203, PSS1204 only. M5×0.8 with4 mm; PT1/8 with6/8 mm; PT1/4 with6/8/10 mm; PT3/8 with10/12 mm; PT1/2 with12 mm. The wider PSL tube/thread combination matrix does not apply to PSS. |
| Suffix and color | A/B control code required; blank grey or D black release button/body. PT blank thread field; M5 metric. No G/NPT, voltage, omitted control code or extra seal suffix in these sources. |
| Operating limits | 0–1.0 MPa working;1.5 MPa proof;−20 to+70°C ambient/fluid;−750 mmHg vacuum. Soft nylon or polyurethane tube. Proof is not continuous working pressure; actual tube compatibility and circuit conditions require confirmation. |
| Needle control and leakage | Needle clockwise reduces controlled flow/speed; counterclockwise increases. Begin from closed and open slowly for actual actuator commissioning. Source explicitly permits some leakage in closed position: not a zero-leak stop valve, safety isolation or pressure-compensated constant-flow regulator. Do not use pliers or force at adjustment limits. |
| Materials | Nickel-plated brass core/needle, aluminium-alloy cap/rings, PBT plastic body/holder, POM location/interface pieces, NBR seals and stainless spring per source structure. Neither all-metal nor copper-free/stainless body. Published anti-drop design does not establish a safety certification. |
| PSS dimensions | PSS-specific table retains tubeD, threadR, insertionL, adjustableCmax/min and weight for all nine pairs. A/B have same external dimensions. 4M5 C30/27.5 mm,weight8.1 g;601 C41.5/35 mm,19 g;1204 C58.5/51.5 mm,105.8 g. Match knob access,360° tube orientation and wrench clearance, not PSL dimensions. |
| Flow-chart conditions | Shared charts explicitly identify PSS size/thread lines. Controlled flow is graphed against needle turns at0.5 MPa; free flow against inlet pressure inMPa, unitsL/min(ANR). Curves are configuration/condition specific, not guaranteed actuator speed or an exact fully-open capacity for every code. |
| Installation and inquiry inputs | Insert cut tube fully; depressurize before release-button removal. Thread torque/insertion depth referenced to actual fitting instructions, there is no single torque specified for all fittings. Send full code, handleA/B, tube/thread photo, direction/circuit, actuator and speed/duty requirement, pressure/temperature, quantity and destination. |

The source explicitly allows some closed-position leakage and does not design it as a zero-leak stop valve. Needle setting and actual pressure/load/circuit influence flow and speed. Confirm A/B direction and commissioning requirements; no constant-flow or safety-isolation guarantee.
