Humphrey | Quick Exhaust Valves | SQE2-VAI

Key Features:
- Quickly redirects exhaust air with high flow capacity via 1/4″ NPT pipe exhaust port
- Operates using a pressure-differential molded shuttle for ultra-fast response
- Dual functionality: can serve as shuttle valve, check valve, or flow control (with plug/orifice)
- Compact inline design for efficient system integration
- High flow rate: CV ~1.42, approx. 85 SCFM at 100 psig
- No lubrication required; durable construction with anodized aluminum, zinc die-cast, and FKM shuttle
- Wide operating range: 4–150 psi, temperature –25 °F to 180 °F

Typical Applications:
- Accelerating cylinder exhaust to increase actuation speed in pneumatic systems
- Acting as shuttle or check valve by plugging or modifying exhaust port
- Enhancing cylinder responsiveness by enabling “air spring” return
- High-cycle automation requiring rapid exhaust handling
