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.

Advantages - Very short refacing time! - No dust! - No noise! - Powered by low operating voltage! Features The machine is fitted with two motors providing a smooth cutting action. The operating voltage supplied to the motors by a compact power supply unit is of the low voltage type to eliminate electric hazards. The exchangeable adapter head with the built-in slideway for cutting tool travel ensures a precise seat angle eliminating faulty setting operations. Roundness, concentricity and surface finish of the refaced valve seat are within manufacturers’ specifications or even better. Handling Setup is fast and easy. First, lock the pilot with mounted centering spider in the valve guide. Then, lower the machine over the pilot and position the cutting tool in front of the inner edge of the valve seat. Turn micrometer downfeed to set the desired depth of cut. Refacing is automatic. Pressing one button is enough to start the refacing pass.

Working Principle: The counterbore is machined to the preset depth by the simultaneous application of both a rotary and vertical or horizontal feed motion to the carbide cutting insert. While the cutting insert rotates in a circle around the counterbore, a feed gear mechanism ensures a continuous feed motion. The lathe-type refacing action provides smooth and closely fitting contact surfaces for oversize valve seat rings. Features: The motor drive unit of the VD4HD-ADM is identical with the motor drive unit of the VD4HD Valve Seat Refacing Machine and, therefore, is only required, if no VD4HD is at hand. Two types of exchangeable boring gear heads are available. The standard AV boring head is provided with a vertical slide for counterboring. The optional AVH boring and facing head is provided with a vertical and a horizontal slide for counterboring and facing the bottom of the bore.

Application The Hunger RDS is designed to precision machine the seat ring bores in cylinder heads to produce smooth and closely fitting contact surfaces for oversize seat inserts. Features The RDS is equipped for counterboring as well as for facing the bottom of seat ring bores in a lathe-type action with a single point carbide cutter. The RDS is aligned in centerline with the valve guide by means of a pilot which is locked in the valve guide. An universal steady stabilizes the RDS against lateral displacement. Pilots and steady furnished with Hunger valve seat refacing tool also suit for the corresponding RDS tool. The built in feed gear mechanism for automatic longitudinal and cross feed of the single point cutter eliminates the need for multiple cutter sets and other accessories. An adjustable stop for the tool slide permits quick selection of the proper sized bore diameter.

Application With the PVM1 assembly set, worn valve guides can be quickly and easily removed from the cylinder head and new valve guides inserted into the cylinder head. The assembly set is particularly suitable for motorcycle, car and commercial vehicle workshops. Features The air hammer can also be used to drive valve seat inserts out of the cylinder head. For this purpose a Hunger valve seat turning device is used to turn a groove into the valve seat ring. The seat ring is driven out of the cylinder head by means of a clamping head whose expandable clamping elements engage in the groove. Handling Insert the appropriate drift pin into the pneumatic hammer and insert the drift pin into the valve guide. Switch on the compressed air supply with the control lever provided on the pistol grip of the air hammer. The valve guide is driven out of or into the cylinder head by the rapid impact sequence. A soft protective ring placed on the drift pin protects the valve guide from damage.

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 VD4HD/-30° can be used for refacing the external conical landing face on valve cages. Capacity Max. refacing diameter 250mm Angle of transverse feed -30° Features Drive unit and gear head of the VD4HD/-30° are identical with the drive unit and gear head of the VD4E Valve Seat Refacing Machine. If a VD4HD is already on hand, only the D4/-30° adapter head is required for refacing the external conical landing face on valve cages. The D4/-30° adapter head is bolted to the gear head in place of the seat refacing adapter head. The pilot used for valve seat refacing can be also used for centering the VD4HD/-30°.

Application The SG 175 support grinder is designed for grinding the conical seating surface of valves of medium speed diesel engines on a standard lathe. Handling The support grinder is clamped in the toolpost located on the top slide of the lathe. The grinding angle corresponding to the required valve seat angle is adjusted by turning the top slide of the lathe to an angular position which corresponds to the valve seat angle and which is defined by the template supplied with the grinder. The valve stem is clamped in the chuck of the lathe and the valve face is ground by feeding the grinding wheel into the rotating valve face. Features The precision grinding spindle is permanetly sealed and lubricated for lifetime accuracy. The wheel guarding system is designed to the prevailing safety regulations. The cone-shaped head of the template is provided with a bore receiving the dressing diamond so that the grinding wheel can be properly dressed after adjustment of the grinding angle.

Probably the most hygienic way of shutting off a flow of media is when the valve does not touch the fluid at all. This is the principle used by this small diameter endless tube valve, in which the fluid is passed through a hose pneumatically compressed or relieved by the valve.
