Get quoteThe 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.
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.
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.
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.
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.
HBQD pneumatic components are manufactured to industrial standards and used widely in Chinese frame production machinery. The 4H210-08 model is compatible with standard corner nailer pneumatic circuits and is designed for the high-cycle demands of production frame manufacturing. XKY Framing stocks genuine HBQD parts for reliable replacement and maintenance.

| Overview | <p>The NN29 Manual Valve (HBQD 4H210-08) is a hand-operated 5/2-way directional control valve for controlling nail feeding on corner nailers. No electrical connection required—a push-lever on the valve body manually shifts air flow to extend or retract the nail feeding cylinder. Used as the primary feed control on pneumatic corner nailers or as a manual override on CNC machines. Connectors: 2-fen elbow push-fit; 1-fen silencer.</p> |

How is the manual valve different from the solenoid valve (NN28)?
The NN29 manual valve is hand-operated by a push-lever on the valve body, requiring no electrical connection. The NN28 solenoid valve is electrically controlled by the CNC machine's PLC. Manual valves are used on pneumatic (non-CNC) corner nailers or as manual override valves.
What connector size does the NN29 use?
The NN29 uses 2-fen (1/4 inch) 4cm elbow push-fit connectors at the working ports and a 1-fen (1/8 inch) silencer at the exhaust port, matching standard corner nailer pneumatic tubing.
Can the NN29 be used with CNC corner nailers?
Yes. While primarily designed as the main control valve for pneumatic corner nailers, the NN29 can also be installed as a manual override valve on CNC corner nailers, allowing operators to manually actuate nail feeding during setup or maintenance.
