VD 3

The simple valve seat refacing system for valve seats up to 200mm in diameter

Application
The VD3 is particularly suited for tough seat materials like Nimonic which, when machined by grinding, tend o load the grinding wheel rather fast.
The VD3 cuts even hard seat materials fast and clean.
The VD3 refaces the valve seat in flawless concentric patterns, providing the best surface texture for a complete valve seal.
When the valve hits the valve seat, the concentric patterns are flattened and perfectly matched with the valve face.
