NN28-Solenoid Valve DC24V for CNC Corner Nailer Nail Feeding

Solenoid Valve DC24V Corner Nailer Nail Feeding – NN28 HBQD 4Y210-03

The solenoid valve DC24V corner nailer nail feeding NN28 is a precision directional control valve that manages the automatic nail feeding cylinder on CNC corner nailers. Electrically controlled by the machine’s PLC at DC 24V, it precisely times the nail feeding sequence to deliver one nail per cycle into the nail die, enabling fast and reliable automatic nailing.

Role of the Solenoid Valve in Nail Feeding

In a CNC corner nailer, the nail feeding system uses a pneumatic cylinder to push one nail from the magazine into the die position for each nailing cycle. The solenoid valve DC24V corner nailer nail feeding NN28 is the electrically-controlled switch that directs compressed air to extend or retract this cylinder on command from the control system. A malfunctioning solenoid valve causes missed nails, double-feeding, or complete nail feed failure.

Electrical and Pneumatic Specifications

The NN28 operates at DC 24V with a power consumption of 4.8W and current draw of 200mA. It is IP65-rated for protection against dust and water splash in workshop environments. The valve body is HBQD Model 4Y210-03, a 5/2-way single solenoid with spring return. Working port connectors are 2-fen (1/4 inch) 4cm elbow push-fit fittings; exhaust port uses a 1-fen (1/8 inch) silencer. A clear indicator lamp on the solenoid coil shows energized status.

Installation and Wiring

Connect the solenoid valve’s DIN connector to the CNC nailer’s DC24V output from the PLC/control board. Connect pneumatic tubing from the main supply to port P, working ports A and B to the nail feeding cylinder, and ensure the silencer is free to exhaust. The clear indicator lamp allows quick visual confirmation that the valve receives control signal during troubleshooting.

Compatibility

The NN28 solenoid valve DC24V corner nailer nail feeding component is compatible with most CNC corner nailers using DC24V control systems and standard 1/4-inch (2-fen) pneumatic tubing for nail feeding circuits. It pairs with the nail feeding cylinder (NN14) and oil-water separator (NN32/NN35) in the complete pneumatic system.

HBQD Quality Assurance

HBQD (Hongbing Pneumatics) manufactures the 4Y210-03 to industrial standards for high-cycle pneumatic applications. The solenoid coil is rated for 100% ED (continuous duty), meaning it can remain energized indefinitely without overheating—important for CNC systems that may hold the valve energized during long production runs.
