Plunger valve: The plunger valve assembly can effectively help the nail gun to drive large heavy nails (framing nails) into wood or other materials and get the job done.
Trigger Valve: The trigger valve assembly pushes the piston forward with tremendous force. The piston drives the nail into the material.
Material: The main body is made of galvanized material, with good gloss and texture, good sturdiness, moisture-proof and rust-proof, and durable.
