This is a genuine head valve for nailers and staplers. The head valve is responsible for controlling the flow of air to the cylinder. When the trigger is pulled, it creates an imbalance of pressure, which opens the head valve and fires the piston. The head valve is prone to wear over time, so it is important to inspect it often. The seals on the head valve or the body itself can begin to harden and eventually crack, and this results in air leaking from the gun exhaust. For this repair you will need an Allen wrench adjustable wrench and a screwdriver. This plastic head valve is sold individually.

This is a manufacturer-approved replacement head valve and is sold independently. It controls the amount of air that enters the cylinder when the trigger is initiated. This action creates an imbalance in pressure between the cylinder and the air reservoir, allowing the head valve to open, firing the piston. The head valve can harden and crack and the valve body itself can break too. This will usually become obvious because air will leak from the gun exhaust. To access this part for the repair, you will need to remove the top cap from the nail gun.

This genuine OEM trigger valve in your nailer or stapler works in conjunction with the head valve. When you press the trigger valve, it creates a pressure difference between the air reservoir and the cylinder and causes the head valve to open and release compressed air to drive the nail or staple into the material you are working on. It is commonly found in the handle or grip area of the tool. If the trigger becomes stiff or difficult to press, the trigger valve may be damaged. To replace the trigger valve, begin by removing the magazine and retainer caps for the nosepiece guard. Take out the nosepiece from the housing and remove the roll pins securing the piston. Pull back the plastic guard on the housing, detach the strap securing the piston, and extract the piston from your tool. You can access and remove the trigger valve by taking out the O-ring and the pin that holds the trigger in place. Before reassembling the housing, remember to apply lubricant to the O-rings.

This item is an authentic Bostitch replacement part that has been sourced from the original manufacturer to be used with pneumatic nailers. The trigger valve works with the plunger to shift pressurized air above the piston to drive it downward and to allow pressure to move back below the piston to keep in the up position. This item is available as an individual replacement part.
