Helpful for Model Matching:
| Function / direction | Air flows in one direction only;follow markedIN→OUT |
| Port / thread | 06=1/8;08=1/4;10=3/8;15=1/2;20=3/4;25=1;PT/G/NPT |
| Operating pressure | 0.02–1.0MPa(2.9–145psi) |
| Opening pressure caveat | Cracking/opening differential pressure is not separately stated;the 0.02MPa minimum operating pressure is not a cracking-pressure rating. |
| Proof pressure | 1.5MPa(215psi) |
| Temperature / body | −20 to+70°C;aluminum alloy |
| Published orifice / Cv | 06:18mm²/Cv1.0;08:27/Cv1.5;10:60/Cv3.33;15:73/Cv4.06;20:230/Cv12.78;25:260/Cv14.44 |
| Medium / sealing | Air filtered through40μm element;POM spool with rubber-sealed core per catalogue feature. |

NRV permits airflow in one direction only and is intended to prevent backflow during pressure drops or reduced air consumption. Select06/08/10/15/20/25 and thread,then verify the actual bodyIN/OUT marking before installation. The minimum operating pressure0.02MPa is not a separately specified cracking pressure;send any opening-pressure or reverse-leakage requirement for confirmation.
The catalogue lists0.02–1.0MPa as operating pressure but does not separately specify the opening differential. Send your required opening pressure,flow and operating conditions for confirmation.
Send the full code,label orIN/OUT photos,quantity and destination. Include port/thread,actual flow direction and any reverse-leakage requirement;an incomplete code can still start a consultation.
