Introduction General description hese solenoid operated directional control valves are for directing and stopping flow at any point in a hydraulic system. his 0-design series has been specially designed and developed to cover expanded demands in the industry as well as the many traditional uses of the earlier designs. Some of the more important benefits to users are outlined. Efficient control of greater hydraulic powers without increasing solenoid power consumption. Installed cost and space savings from higher power/weight-and-size ratios. Increases system efficiency; the result of improved manufacture of spools and bores. Installation flexibility resulting from choice of numerous combinations of solenoid connectors and locations. Multi-fluid capability without need to change seals. Higher sustained machine productivity and higher uptime because of proven fatigue life and endurance, tested over 0 million cycles. Solenoid coils can be changed quickly and easily without leakage from hydraulic system. Compact, cost effective system design when used with Vickers SystemStak valves and subplates. DGV-3 and DGV-3S High and standard performance models: Up to 80 l/min (1 USgpm) and up to 0 l/min (10.

DGV-3 models are direct solenoid operated four-way directional control valves.heir primary function in a hydraulic circuit is to direct fluid flow. his, in turn, would determine the direction of movement of a fluid cylinder, or the direction of rotation of a fluid motor. ort connections are made by mounting the valve on a subplate or manifold. he valve has wet armature type solenoids. Electrical connections to the valve are made in the electrical wiring housing or thru various plug-in connectors such as a DIN 30 type coil Good hydraulic design practice suggests that detented models be mounted with longitudinal axis horizontal. Other models may be mounted in any position. Operating considerations 1. Dependent on the application and the system filtration, any sliding spool valve if held shifted under pressure for long periods of time, may stick and not move readily due to fluid residue formation. It may therefore need to be cycled periodically to prevent this from happening.. Surges of fluid in a common tank line serving two or more valves can be of sufficient magnitude to cause inadvertent shifting of these valves. his is particularly critical in no-spring detented models, separate drain lines are necessary.

For synthetic fluids, consult fluid manufacturer or Vickers representative where limits are outside those for mineral oil. Whatever the actual temperature range, ensure that fluid viscosities stay within the limits specified in Hydraulic Fluids. Fluid Cleanliness roper fluid condition is essential for long and satisfactory life of hydraulic components and systems. Hydraulic fluid must have the correct balance of cleanliness, materials and additives for protection against wear of components, elevated viscosity and inclusion of air. Essential information on the correct methods for treating hydraulic fluid is included in Vickers publication 1; Vickers Guide to Systemic Contamination Control, available from your local Vickers distributor or by contacting Vickers, Incorporated. Recommendations on filtration and the selection of products to control fluid condition are included in 1. Recommended cleanliness levels, using petroleum oil under common conditions, are based on the highest fluid pressure levels in the system and are coded in the chart below. Fluids other than petroleum, severe service cycles or temperature extremes are cause for adjustment of these cleanliness codes. See Vickers publication 1 for exact details. Vickers products, as any components, will operate with apparent satisfaction in fluids with higher cleanliness codes than those described. Other manufacturers will often recommend levels above those specified. Experience has shown, however, that life of any hydraulic components is shortened in fluids with higher cleanliness codes than those listed below. hese codes have been proven to provide a long trouble-free service life for the products shown, regardless of the manufacturer. Fire resistant fluids usually have higher specific gravities than oil. he specific gravity of a fluid may be obtained from its producer.
