The NG-SHM Class DP – Servo Hydraulic Testing Machine is equipped with a logic valve and advanced pressure servo technology that ensures intelligent regulation of hydraulic system pressure. This setup maintains the system pressure within 1MPa above the cylinder pressure, which provides stable and efficient performance. By automatically adjusting the pump output pressure in response to the test force, the system optimizes energy use and minimizes mechanical stress.

When the applied test force is low, the system reduces the pump pressure to save energy and reduce wear. As the test force increases, the pump output is raised to match the cylinder’s needs, resulting in consistent and safe operation. This real-time pressure adjustment contributes to accurate force application, lower noise, reduced heating, and longer service life for hydraulic components. This smart regulation system is a key feature that enhances performance, reliability and operational efficiency in high-precision material testing.
