5219ATOS HM Modular Relief Valves.

ATOS Solenoid Directional Valves


ATOS HM modular relief valves are double stage pressure relief valves with a balanced poppet. The pressure adjustment is operated by loosening the locking nut and turning the screw protected by the cap. Optional versions with setting adjustment by hand-wheel instead of the screw are available upon request. In order to increase the pressure, clockwise rotation is required.

HM = ISO 4401 size 06 interface; maximum flow 35 l/min; maximum pressure up to 350 bar.

The ATOS HM modular relief valves are designed to operate in hydraulic systems with hydraulic mineral oil or synthetic fluid having similar lubricating characteristics. Modular relief valve ordering codes/data can be found on the attached data sheet.
