Overview
The SMC AQ3000-N03 is a quick exhaust valve from SMC’s AQ series, engineered for pneumatic automation and control applications. This valve is designed to rapidly vent pilot pressure, enabling fast actuation cycles and improved system response. The compact aluminum body with diaphragm-style sealing makes it ideal for space-constrained installations while maintaining high flow efficiency.
Key Features
- High flow capacity with low differential pressure drop
- Compact and lightweight aluminum construction
- Available in diaphragm or lip seal configuration
- 3/8 NPT (female threaded) connections
- Nitrile seal material for standard pneumatic applications
- One-touch push-fit fitting compatibility available in AQ series variants
