1 efore using the product, please check the For latest information, DF catalogs and operation manuals Direct Operated ype Solenoid Operated roportional hrottle Valve EM-G EM-G3 EM-G3-X EMS-2 EMS-2 EM-G4 b X EMS-3 Features hese proportional throttle directional control valves perform spool position feedback control by directly driving the spool with the proportional solenoid and detecting the displacement with the differential transformer. Combining the valve with a pressure compensation valve and the dedicated driver achieves highly accurate proportional flow rate control. Highly accurate proportional flow rate control with meter-in control at port or meter-out control at port can be realized by stacking the EMS valves in combination with the dedicated reduction type pressure compensation valve (MGS) under the solenoid valve.

Handling Directly connect the tank and drain piping to the tank without merging it with other tank piping. Do not touch the zero adjusting screw of the differential transformer since it is factory adjusted. Use this valve in combination with a pressure compensation valve. Order a pressure compensation valve separately by referring to the table below as necessary.
