Pressure can be maintained at the preset pressure for the pressureswitch.SMP-30 (40)*2BSMP-30 (40)*4BSMP-30 (40)*6BWhen the remote controlled operating switch is turned ON, if the lever ofthe direction-control manual valve is turned clockwise, the single-actingcylinder is extended. Pressure can be adjusted and maintained using the relief valve attachedto the pump. (Pressure adjustable range: 10 to 70 MPa)SMP-30 (40)*2BRSMP-30 (40)*4BRSMP-30 (40)*6BRSMP-30 (40)*2SKWhen the remote controlled operating switch is turned ON, the single-acting cylinder is extended. The maintenance of pressure and theextension of the cylinder (the stopping accuracy is poor) are possibleduring pressurization. If the remote controlled operating switch is turnedOFF and then the RETURN button is pressed, the cylinder is retracted.The cylinder cannot be stopped once it starts being retracted.SMP-30 (40)*4SKSMP-30 (40)*6SKWhen the remote controlled operating switch is turned ON, the single-acting cylinder is extended.The single-acting cylinder is automatically retracted at the presetpressure for the pressure switch.The pressure cannot be maintained and the cylinder cannot be stoppedhalfway.SMP-30 (40)*2ARSMP-30 (40)*4ARSMP-30 (40)*6ARThe single-acting cylinder is extended or retracted only while the PUSHor PULL button of the remote controlled operating switch is pressed andheld. The cylinder can be stopped while pressure is applied.The pressure can be maintained while the PUSH button is pressed andheld. The cylinder can be stopped at any position while it is beingretracted (under no load condition).SMP-30 (40)*2RKSMP-30 (40)*4RKSMP-30 (40)*6RKSMP-30 (40)*2NEThe single-acting cylinder can be extended or retracted only whilethe PUSH or PULL button of the remote controlled operating switch ispressed and held.
