2 Solenoid Operated Directional Valve DG4V-3- Design (Soft Shift Design) General Description These solenoid operated directional control valves are for directing and stopping flow at any point in a hydraulic system. The soft shift feature is designed to provide smoother control of actuator acceleration and deceleration than is possible with conventional solenoid valves. The result is minimum hydraulic shock, more reliable systems with longer component life and less downtime. There are options for the soft shift feature: 1. Variable orifice design where you can use an optimized damping orifice tuned to suit your application.. A fixed orifice design, which is non-serviceable and cannot be tuned. Features & Benefits Milled metering notches on the spool enable precise control of flow rate change as the spool is shifted. A P1L - model offers a junction box with rectifier, lights and plug-in coils for quick and easy solenoid changing without removing the valve from the machine. - EATON Solenoid Operated Directional Valve DG4V-3- E-VLVI-SS1-E1 October 15

5 Operating Data Response Time Response times are increased over that of a standard solenoid. These times are influenced by flow, pressure, applied solenoid voltage, oil viscosity and ambient temperatures. Response times can be fine tuned to the application by orifices that are interchangeable via the manual actuator in the solenoid end. See model code for available orifices. Response times shown are for a type spool at a system pressure of 1 bar (3 psi), flow at 19 L/min (5 USgpm), solenoid voltage at 1% of rating and 38º (1º F) oil temperature. Times are determined from the instant of power on/off to the point of maximum cylinder velocity (shift) or the end of cylinder movement (spring return). All times are without arc suppression diodes. Spring return times can be expected to increase with diodes in place. Response times greater than 7 msec are not recommended. NOTE: For the high performance type 8 model, core tube orifice sizes smaller than. mm diameter are not recommended. For Variable Orifice() Orifice Response Times olor Diameter Shift Spring ode mm (ms) Return (ms), Green, Blue,9 5 5 Purple Response times for spools other than the spool are similar and are system dependent. For Fixed Orifice(3) Response Times Shift Shift (ms) Return (ms) Response times for spools other than the spool are similar and are system dependent. Orifice hanging Procedure WARNING 1. Before breaking a circuit connection make certain that power is off and system pressure has been released. Lower all vertical cylinders, discharge accumulators and block any load whose movement could generate pressure. Plug all removed units and cap all lines to prevent entry of dirt into the system.. Using a 5/3 hex key, remove manual actuator plug and spring from the end of solenoid (Tightening torque. 7.3 N.m 55 5 lbf.in.) 3. Insert extraction tool (878495) into solenoid via the manual actuator opening. Rotate tool until aligned and push pin into slot in armature. 4. Using 1/ wrench and tool to prevent the armature from rotating, insert 3/3 hex key down the center of tool and remove orifice plug. 5. Replace by the same method, tightening orifice snug to ensure bottoming of threads. Smaller orifices increase response times, larger orifices decrease response time. Orifice & Tool Kit For fine tuning shift performance, orifices must be ordered separately. The kit includes () each of.7,.8 &.9 mm dia. orifices, (1) installation tool, (1) 5/3 hex key and (1) 3/3 hex key.
