The spouted hydraulic fluid may cause　injury to nearby workers. The direction of the hydraulic oil spout should be carefully considered as it may contaminate the surrounding area.● When the valve is activated, the internal packing is damaged, so hydraulic fluid will continue to be released from the safety valve even if the　pull-side pressure drops. Therefore, if the cylinder is installed in a direction where the piston extends downward, be careful of the piston　falling down its own weight after the valve is activated.● When the valve is activated, be sure to investigate the cause of the blockage on the pull side and solve the problem before replacing a　new safety valve.Maximum operating pressureMaximum outputEffective areaCylinder internal diameterStrokeCylinder systemReturn systemCoupler connection port size* The piston may not be returned to the stroke-end by the return spring force depending on the aged deterioration or the operating conditions. ■Compatible attachmentsAttachment locationCylinder partsPiston thread(MSP05/SP1)Cap thread(SP05)Collar thread* Clevis for 100 kN cannot be used with SP1-150.

Remove the orifice plug when plumb drain port. ■CSV-R344R3-
