1. Features

1.1 Automatic hydraulic clamping, big and adjustable clamping force, equipped with gauges displaying
corresponding clamping forces, pre-clamping available, the clamping cabinet’s wetted section
components are stainless steel. Compare with similar products of other brands:

• the same valve size, Good Gear products can test bigger set pressure;
• the same set pressure, Good Gear products can test bigger valve size;
• provide quicker and more accurate clamping force.

1.2 Test various relief valves such as full-open, micro-open, imperial, metric, flanged and threaded etc.

Compare with similar products of other brands: have years of experience in design and producing Safety Relief Valve test bench, Good Gear has obvious advantages at techniques, test
