Concentric valves - Import export

Application The VD2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships. Features The VD2 refaces the valve seat in a lathe-type facing action. The tool head includes two inclined slideways for refacing 30° and 45° valve seats. A single point turning tool is clamped to tool slide guided in the respective slideway. When the VD2 is rotated around the pilot by hand, the turning tool travels in a circle around the valve seat with continuous outward transverse feed motion under the correct seat angle. A steady rest which is mounted on the cylinder head stabilizes the VD2 below the crank handle. The steady rest eliminates runout when rotating the VD2 around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.

Application The VDS2 is designed to reface valve seats of the engines of trucks. heavy construction vehicles and small ships. Features The VDS2 refaces the valve seat in a lathe-type facing action. A gear head includes a feed mechanism for continous outward transverse motion of the single point turning tool when the VDS2 is rotated around a pilot inserted in the valve guide. The direction of the feed motion is defined by an exchangeable adapter head screwed to the gear head. A steady rest which is mounted on the cylinder head stabilizes the VDS2 below the crank handle. The steady rest eliminates runout when rotating the VDS2 around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.

Application The VDS1A is designed to reface valve seats of the engines of motorcycles, cars and light commericial vehicles. Features The VDS1A refaces the valve seat in a lathe-type facing action. A gear head includes a feed mechanism for continous outward transverse motion of the single point turning tool when the VDS1a is rotated around a pilot inserted in the valve guide. The direction of the feed motion is defined by an exchangeable adapter head screwed to the gear head. A steady rest which is mounted on the cylinder head stabilizes the VDS1A below the crank handle. The steady rest eliminates runout when rotating the VDS1A around the pilot. As a result, the seat is refaced to concentricity with the valve guide under the correct seat angle.
