Features of the Model K & K Universal

Valve Compatibility: The Model K & K Universal is suitable for a wide range of valves, including globe, control, and safety valves. It can grind flat seats with a diameter of 8mm to 150mm and angled seats with a diameter of 8mm to 65mm. This makes it an ideal tool for valve maintenance in the industrial sector.

Drive Unit: The Model K Universal allows the user to use a standard drilling machine of their choice as the motor. Alternatively, it is available with a compressed air drive unit (6 - 7 bar), electric battery drive unit, or electric 110/220V drive unit (Model K only). This flexibility enables users to select the most suitable drive unit for their application.

Grinding Discs: The Model K & K Universal requires only three sizes of abrasive grinding discs for the full seat size range, making it a cost-effective solution. It comes with rough, medium, and fine grinding discs, which are self-adhesive for quick attachment to the grinding heads. Self-adhesive grinding discs with grit sizes ranging from 40 to 1000 are also available. Extended grinding plates and diamond grinding discs can also be purchased as optional extras.

Variable Grinding Speed: All drive units are reversible and have a variable grinding speed (Model K only). This feature provides greater control over the grinding process, enabling the user to adjust the speed according to the valve type, material, and condition.

Guiding Plates: The Model K & K Universal includes guiding plates for more precise grinding. These plates ensure that the grinding head moves in a straight line and maintains a consistent angle, resulting in an accurate and uniform grind.

Carrying/Storage Case: The Model K & K Universal comes with a heavy-duty carrying/storage case that stores the complete machine and all necessary accessories. This case protects the machine during transport and ensures that all components are stored in one place, preventing loss or damage.
