Transportable grinding machine for safety valves (TSV)

In essence, the aim is to quickly make safety valves leak-proof again, and this is what the transportable Grinding machine for safety valves (TSV) is designed for. As a valve repair machine (transportable), it brings the processing directly to the valve and saves dismantling paths.

Unlike simple devices, it works as a valve Grinders Valves with stable guidance for reproducible seating surfaces. In the larger system, two separate drives are standard so that the grinding movement and additional movement run independently. This makes on-site valve machining possible even in confined spaces, and mobile valve seat machining remains easy to plan.

In everyday working life, you will quickly see what a portable Grinding machine for safety valves (TSV) is good for. It supports maintenance and repairs directly on the valve without having to take everything to the workshop.

Particularly during system downtimes, grinding the sealing surface for safety valves helps when the seat and sealing edge need to be clean again. You can also grind a safety valve with an immersion depth of 350 mm if the geometry is deeper. Technically, this is suitable for many industrial valves, and EFCO's quality standard is ISO 9001 2015.

During everyday servicing, you often come across sealing surfaces that need to close cleanly again, and this is exactly where a portable Grinding machine for safety valves fits in. Typical areas are seat rings, seat cones and flat sealing surfaces on the valve body as well as the mating surface on the cone or disc.

Safety valves with and without flanges can also be ground if the contact surface or sealing edge is damaged. This is practical both as a stationary Grinding machine in the workshop and in the testing area. For larger valves, the TSV series covers up to DN 25 to 300 mm.

In use, it quickly becomes clear why a transportable Grinding machine for safety valves uses the eccentric movement. The additional lateral movement ensures that the material is removed evenly over the entire sealing surface instead of taking away more material on the inside or outside. This reduces the risk of the seat surface becoming crooked and not sealing properly later on.

This makes the valve sealing surface grinder more stable, especially during on-site valve repairs, regardless of whether it is used as a stationary or mobile grinder. With the TSV-150 DN 15-150 Grinding machine, speeds of up to around 560 rpm are possible.

In practice, you do not select the valve size by feel, as the transportable Grinding machine for safety valves is selected according to the seat diameter and accessible installation position. For smaller and medium-sized safety valves, a compact set is often sufficient if the seat is easily accessible and the guide is stable.

For larger nominal diameters and heavier valves, the TSV-300 DN 25-300 grinding and lapping machine for safety valves comes into play. The maximum supply of 230 V at 50 or 60 Hz also helps if no compressed air supply is available on site.

In principle, you can use a Grinding machine for safety valves (TSV) for on-site repairs if the valve seat is accessible and the machine can be securely fixed in place. On site, you save dismantling time and keep downtimes to a minimum.

A suitable power supply is important, as the system runs with 6 to 7 bar compressed air or with 110 or 230 V at 50 or 60 Hz, depending on the version. This ensures that processing remains realistic even on construction sites. If you only have a short-term requirement, rental via EFCO Rental is an obvious option.
