Manual Valve Corner Nailer Nail Feeding Control – NN29 HBQD 4H210-08
The manual valve corner nailer nail feeding control NN29 is a hand-operated pneumatic directional valve that provides simple, reliable control of the nail feeding cylinder on corner nailers. Unlike electrically-controlled solenoid valves, the NN29 requires no wiring or control system—making it the ideal solution for pneumatic corner nailers and for manual override applications on CNC machines.
Hand-Operated Pneumatic Control
The manual valve corner nailer nail feeding control NN29 uses a push-lever mechanism to manually shift the 5/2-way valve between its two positions. In position A, compressed air extends the nail feeding cylinder to push a nail into position. In position B, the cylinder retracts to allow the magazine to advance the next nail. The operator controls the timing directly, giving full manual control over nail feeding without relying on electronic systems.
HBQD 4H210-08 Specifications
The NN29 is HBQD Model 4H210-08, a 5/2-way manually-operated toggle valve with spring detent (maintained position). Working port connectors are 2-fen (1/4 inch) 4cm elbow push-fit fittings compatible with standard corner nailer pneumatic tubing. The exhaust port uses a 1-fen (1/8 inch) silencer to reduce exhaust noise. The push-lever handle is ergonomic black plastic for comfortable hand operation.
Applications
The manual valve corner nailer nail feeding control NN29 is used on: pneumatic tabletop corner nailers as the primary nail feed control valve, CNC corner nailers as a manual bypass/override valve during maintenance and setup, and any corner nailer where electrical control of nail feeding is not required or has failed. It provides the same pneumatic function as the solenoid valve (NN28) but without the electronic dependency.
Comparison With Solenoid Valve NN28
Both the NN28 solenoid valve and NN29 manual valve control the nail feeding cylinder on corner nailers, but through different means. Use NN28 for automated CNC applications requiring machine-timed nail feeding. Use NN29 for manual or semi-manual pneumatic nailers, or as a backup control valve. Both use the same 2-fen elbow connectors and 1-fen silencer for easy installation.
