Bostitch tva6 Trigger Valve Kit Pneumatic Nailer

Product Description

The BOSTITCH tva6 is a trigger valve kit designed to restore proper firing function in compatible pneumatic nailers. The trigger valve is a critical internal component that controls air flow and initiates the drive cycle when the tool is actuated. Over time, this valve can wear or sustain damage from debris, oil contamination, or repeated cycling, resulting in misfires, double fires, or complete loss of function. This kit provides the replacement trigger valve needed to return the tool to factory performance. It is installed by pneumatic tool repair technicians and experienced tradespeople familiar with air tool service procedures.

This trigger valve kit is suited for service and repair applications in residential and commercial construction environments. It is commonly used by framing crews, roofing contractors, and finish carpenters who rely on pneumatic nailers for daily production work. Keeping a replacement trigger valve on hand reduces tool downtime on the job site. Compatible manufacturer part numbers include 650S4-1, F21PL, F28WW, F33PT, N62FNK-2, N80CB-1, and RN46-1.

Installation Notes

Trigger valve replacement should be performed by a qualified pneumatic tool technician or a tradesperson experienced with air tool disassembly. Disconnect the air supply line and verify the tool is fully depressurized before beginning any disassembly. Follow the tool manufacturer's service manual for the correct disassembly sequence and reassembly torque guidance. Improper installation can result in air leaks or unsafe tool operation.
