Parallel Slide, Gate Valves, Discs and Wedges Maintenance and Reconditioning

Model S - Suitable for valves with flat seats 25 - 150mm (1” - 6”)

Valve grinding is a critical maintenance process for ensuring the smooth operation of gate and parallel slide valves, discs, and wedges. Over time, these valves can experience wear and tear, leading to leaks and reduced efficiency. The valve grinding process involves removing any rough spots and debris from the valve seats, restoring the original dimensions and surface finish.

Model S Features and Benefits

The Valve Grinding Model S is a high-quality valve grinding machine that is suitable for a wide range of valve sizes. It is designed to handle gate and parallel slide valves, discs, and wedges with ease. The machine is powered by either an air drive unit or an electric drive unit, providing flexibility and convenience.

One of the standout features of the Valve Grinding Model S is the 3° angle grinding plates that come as standard. These plates ensure that the valve seats are ground at the optimal angle, promoting a tight seal and reducing the risk of leaks. In addition, the machine boasts a variable grinding speed on all drive units, allowing for greater precision and control.

The Valve Grinding Model S is also incredibly user-friendly. It comes with a mounting plate for grinding discs and wedges, simplifying the setup process. The machine requires only three sizes of abrasive discs to cover the full seat size range, reducing the need for multiple accessories. Additionally, it comes with a heavy-duty carrying/storage case, ensuring that all necessary accessories can be easily transported and stored.

Another convenience feature of the Valve Grinding Model S is the self-adhesive grinding discs. These discs can be quickly attached to the grinding heads, speeding up the grinding process. The machine comes with rough, medium, and fine grinding discs, but self-adhesive grinding discs ranging from 40 to 1000 grit are also available. For even greater durability and efficiency, diamond grinding discs can be used.
