Visual Seat Leakage Testing with Seatinspec

Visual seat leakage testing is a critical part of modern valve testing processes. Especially for larger nominal diameters, measuring leakage alone is often not sufficient – identifying the exact location of leakage at the valve seat is essential for efficient maintenance and repair.

With Seatinspec, METRUS provides an effective solution for visual valve seat inspection and leakage analysis.

A specially designed spacer is inserted between the valve and the pressure head without the need for tools. This creates sufficient space to inspect the relevant area from the pressure-free side using an endoscope camera.

Accurate Leak Detection at the Valve Seat

By combining leakage testing with visual inspection, Seatinspec enables:

• precise localization of leaks
• targeted correction of valve seat defects
• reduced downtime
• more efficient testing and maintenance processes

This approach is particularly beneficial for valves with large nominal diameters.

Easy Integration into Existing Test Setups

Seatinspec can be easily integrated into existing test environments:

• tool-free installation
• inspection from the pressure-free side
• compatible with existing test benches

The included endoscope camera ensures flexible and user-friendly operation.

Typical Applications

• Valve seat leakage testing
• Visual leak detection in large valves
• Maintenance and repair processes
• Root cause analysis of leakage issues
