Plunger Valve and Trigger Valve Replacement for Hitachi Framing Nailer

The SP-P3 Plunger Valve and Trigger Valve Replacement is designed for Hitachi NR83A, NR83A2, NR83A2(S), and NR83A3 Framing Nailer, with the part number 884-111 and 875-638. This kit includes the Trigger Valve and Plunger Valve components.

The Plunger Valve part number is 884-111. It is essential to confirm that this is the correct product number for your specific model before making a purchase.

This replacement kit is compatible with the following Hitachi Framing Nailer models: NR83A, NR83A2, NR83A2(S), and NR83A3.

The Plunger Valve is made of high-quality brass, while the Trigger Valve's main body is constructed from durable galvanized material. This ensures excellent gloss, texture, and sturdiness, as well as moisture-proof and rust-proof properties for long-lasting performance.

The Plunger Valve assembly controls the movement of the driver or piston within the nail gun, allowing compressed air to push the driver forward to drive nails into the material. It must seal effectively to maintain the air pressure required for proper nail actuation.

The Trigger Valve assembly, on the other hand, controls the flow of compressed air to the Plunger Valve and driver. When the trigger is pulled, the valve opens, and compressed air is allowed to flow to the Plunger Valve. The trigger must be pressed against the work surface before it can be pulled to ensure safe and accurate nail placement.

By replacing the Plunger Valve and Trigger Valve with this kit, users can restore the proper functioning of their Hitachi Framing Nailer, ensuring consistent and reliable nail driving performance.
