The ATOS KG-033/100 is a high-performance, pilot-operated pressure relief valve designed for subplate mounting. It is engineered to limit the maximum pressure within a hydraulic circuit, protecting system components from overpressure damage. This model features a built-in solenoid valve that allows for remote venting or unloading of the circuit, dropping the pressure to a minimal value when energized or de-energized (depending on the solenoid configuration). This functionality is ideal for applications requiring pump start-up under no-load conditions or for creating safety circuits. The valve conforms to the ISO 4401 size 06 (CETOP 03) mounting standard, ensuring easy integration and interchangeability in industrial hydraulic systems.
