QE quick exhaust valves provide a local exhaust path for pneumatic circuits. Four connection sizes cover QE-01 through QE-04, with an aluminium-alloy body and NBR sealing. Select the connection size and check the pressure rating on the supplied configuration.

| QE-02 | 02 | 1/4″ |
| QE-03 | 03 | 3/8″ |
| QE-04 | 04 | 1/2″ |
| Parameter | QE-01 / QE-02 / QE-03 / QE-04 |
|---|---|

| Series operating pressure range | 0–0.8MPa |
| Working temperature | 0–70°C |
| Body | Aluminium alloy |
| O-ring | NBR |
| Weight | Not specified |
The illustrated QE-04 is marked 1.5–8kgf/cm². Use that configuration-specific range when selecting the pictured version; the wider series range does not override its nameplate.
The symbol identifies the supply connection P, working connection A and exhaust connection R. Match the circuit to these markings when installing the valve.
