Pressure can be maintained at the preset pressure for the pressure switch.A heavy load can be prevented from falling by its own weight for smoothoperation of the cylinder.SMP-30 (40)*2DCBSMP-30 (40)*4DCBSMP-30 (40)*6DCBSMP-30 (40)*2SLOnly while the PUSH button of the remote controlled operating switchis pressed and held, oil is discharged from port B and the pump stopsautomatically at the preset pressure for the pressure switch, maintainingthe pressure. Only while the PULL button is pressed and held, oil isdischarged from port A. As soon as the button is released, the outlet portis switched to B, and the amount of oil for the inertia of the motor isdischarged from port B. SMP-30 (40)*4SLSMP-30 (40)*6SLSMP-30 (40)*2SWThe double-acting cylinder can be extended or retracted only while thePUSH or PULL button of the remote controlled operating switch ispressed and held.Because of its good responsiveness, the pump can stop the cylinderimmediately. The pressure can be maintained at the preset pressurefor the pressure switch.SMP-30 (40)*4SWSMP-30 (40)*6SWSMP-30 (40)*2SPThe double-acting cylinder can be extended or retracted only while thePUSH or PULL button of the remote controlled operating switch ispressed and held, maintaining pressure at the preset pressure for thepressure switch. If the button of the remote controlled operating switchis released, port P is blocked for ABT connection and pressure is nolonger maintained.
