Quick Exhaust Valve Corner Nailer Pneumatic – NN27 HBQD QE-03
The quick exhaust valve corner nailer pneumatic NN27 is a high-performance pneumatic component that significantly increases your corner nailer’s cycle speed. By exhausting compressed air directly at the cylinder rather than through the main control valve, it enables faster cylinder retraction and shorter cycle times—a critical factor in high-volume frame production.
How a Quick Exhaust Valve Improves Corner Nailer Performance
In a standard pneumatic circuit, exhaust air from the cylinder must travel back through the connecting tubing and the solenoid or manual valve before being released to atmosphere. This creates backpressure that slows cylinder retraction. The quick exhaust valve corner nailer pneumatic NN27 installs directly at the cylinder port, opening a large exhaust path the moment the control valve reverses, venting air instantly and locally. The result is dramatically faster retraction with no backpressure restriction.
Product Specifications
The NN27 is HBQD Model QE-03, featuring a bright blue anodized aluminum body measuring 145mm in total length and 35mm in height. It uses 3/8-inch (3-fen) push-fit straight connectors compatible with standard corner nailer pneumatic tubing. The built-in exhaust silencer/muffler on the exhaust port reduces operational noise, creating a more comfortable working environment.
Installation on Corner Nailers
Install the quick exhaust valve corner nailer pneumatic NN27 directly at the cylinder’s exhaust port using the push-fit connectors. Connect the inlet to the control valve output line, the cylinder port to the cylinder, and allow the exhaust port (with muffler) to vent freely. No special tools are required—push-fit connections make installation quick and leak-free.
Compatibility
The NN27 is compatible with CNC corner nailers, tabletop corner nailers, and 7- or 8-cylinder corner nailers that use 3/8-inch pneumatic tubing. It works alongside XKY Framing’s solenoid valves (NN28), manual valves (NN29), and pneumatic valves (NN33) in the nailer’s pneumatic circuit.
