If the pressure differential at each port exceeds the values in the table below, valve leakage may occur.
Brown [Red] When two switches are connected in series, a load may malfunction because the load voltage will decline when in the ON state. The indicator lights will light up if both of the switches are in the ON state.
Cylinder piston spd When auto switches are used in mid position on a rylinder with high piston speeds, the auto switch may malfunction. The maximum piston speed which will allow the switch to function is determined by the lollowing formula.
It a lubricant has been used in the system, contjnue to lubricate as the original lubricant applied during manulacluring may have been washed away. The NvJ3000 may be used as a N.C. or N.o. 3 way valve by plugging one ol the A, B ports. Be sure not to plug the exhaust ports.

If exceeding that value, fitting may damaged and tubing may burst. 2 The value of the max. operating pressure is at a temperature of 20C. Refer to the burst pressure characteristics curve for other temperatures. Avoid abnormal temperature rises which may burst the tubing. 3 The values of the min. bending radius is at a temperature of 20C.

It may not be possible to connect the tubing, or leakage or disconnection may occur after connecting. 1. Maintenance operations Improper handling of compressed air is dangerous.
There may be circumstances where a seal or an Oring deteriorates, causing leakage. 10 11 SMC'S GLOBAL MANUFACTURING, DISTRIBUTION AND SERVICE NETWORK EUROPE SLOVENIA SMC Slovenia d.o.o.

OThe valve may be used in low tsmpsrature applications down to 26"F it the air is sutficiently tree of moisture. Please use an appropriate dryer to ensure dry air and prevent the valve lrom freezing. OThe double solenoid valve must be energized for at least 0.1 second o( more to enaurg proper operation.
