Humphrey 3/4 pipe QE5 large quick exhaust valve is versatile. Product redirects exhausting air to its high flow 3/4 pipe exhaust port by sensing pressure differential. May be used as a shuttle valve, or achieve excellent check or flow control function with addition of plug or orifice. Compact body has high flow capacity. Molded shuttle outperforms competitive sheet stock types.
- High airflow capacity Delivers up to 395 SCFM at 100 PSI for rapid exhaust in pneumatic systems.
- Versatile functionality Can be used as a quick exhaust valve, shuttle valve, or check valve with a plug.
- No lubrication required Maintenance-free design for cleaner and more reliable operation.
- Compact & durable build Die-cast aluminum body with molded internal shuttle ensures durability and performance.
