The NG-SHM Class DP – Servo Hydraulic Testing Machine is equipped with a pressure overload protection system designed to safeguard the hydraulic system from excessive pressure levels. This is achieved through the use of a relief valve, which activates automatically when system pressure rises above its rated threshold. When triggered, the relief valve allows excess hydraulic fluid to overflow safely, preventing damage to the internal components.

This feature is necessary for protecting key parts such as seals, cylinders, and servo valves from overpressure, which can lead to leaks, ruptures, or system failure. By making sure that the system operates within safe pressure limits, the overload protection mechanism maintains the reliability and safety of the machine during all types of testing procedures. It also reduces downtime and repair costs by preventing avoidable damage, contributing to the long-term durability and consistent performance of the equipment in demanding material testing environments.
