 Key attributes

Critical Overload Protection
  Prevents Pressure Spikes – The core function of these relief valves is to prevent excessive pressure buildup in the hydraulic system. When pressure exceeds the preset limit, the valve opens to allow hydraulic fluid to flow back to the reservoir, protecting components such as hydraulic motors, cylinders, pipelines, and pumps from overpressure damage.
