Model G - Suitable for valves with flat seats ø 150 - 1300 mm (6” - 52”)

Valves play a critical role in regulating fluid and gas flow in industrial processes. To ensure that they function properly, their sealing surfaces need to be smooth and flat. This is where valve grinding comes in. Valve grinding is the process of smoothing and flattening the sealing surfaces of valves, ensuring proper sealing and optimal performance.

Valve grinding can be a challenging task, especially when dealing with large valves. However, with the right equipment, it can be made easier and more efficient. The Model G valve grinding machine is designed to tackle the most challenging valve grinding tasks, including gate, parallel slide, globe, check, safety and control valves, discs, and wedges.

The Model G valve grinding machine is suitable for valves with flat seats ranging from ø 150 - 1300 mm (6” - 52”). One of the unique features of this machine is its tilting driving head. This feature gives the user the flexibility to grind both gate and globe valves with the same drive unit. This saves time and effort, making the grinding process faster and more efficient. The Model G valve grinding machine has individually driven grinding heads, which ensure an absolute flat sealing surface. The driving heads have diametrically adjustable grinding heads, which enable the operator to achieve a perfect fit between the valve and the grinding head. The machine comes with an air drive unit as standard, operating at 6 - 7 bar. However, an electric drive unit is available as an alternative, offering more flexibility.

The Model G valve grinding machine features a variable grinding speed on all drive units. This allows the operator to adjust the speed to match the specific valve being ground, ensuring optimal results. The machine comes with self-adhesive grinding discs, which can be quickly attached to the grinding heads. It also comes with rough, medium, and fine grinding discs, and self-adhesive grinding discs ranging from 40 to 1000 grit are available. The Model G valve grinding machine comes with a heavy-duty carrying/storage case that holds the complete machine and all necessary accessories. This ensures that the machine is protected and easy to transport. Additionally, the machine comes with optional extras, such as diamond grinding discs, adaptor plates for wider seats, thin section driving heads, and grinding heads for angled seats.
