Units See individual service and repair policies, available from your Vickers representative.
Sizes 16 to 63 The adjustable poppet lift limiter restricts flow from A to B. Inserts used for the relief function or combination relief and unloading functions are D10 models. Opening the pilot throttle valve Figure 40 lowers the pressure in volume 3 allowing the dib poppet to move off its seat. Often, the most economical system incorporates combinations of manifold mounted spool valves and screw-in and slip-in cartridge valves.

Electrohydraulic proportional control of pressure is also available. Y For thread sizes and orifice kits see page Dynamic function is suited for directional or check control functions requiring fast response. See installation drawing, next page. Diameter, mm inches Thread Diameter, Thread mm inches 1,4 0.
UNF threads for orifices See page for sizes of factory-fitted standard orifices. Features and Benefits The HFV range with its simplicity, cost effectiveness and performance level can be applied in almost all applications from high performance industrial areas such 42342 injection molding to those applications just requiring proportional functionality.
Robustly protected switch assembly. Economies are realized and the system is optimized.
Omit W from model code positionsee page This feature is of benefit in any application where there must be absolutely no risk of the cartridge even momentarily opening during pilot pressure changeover. The application would have pump flow going into port B, port A connected to the actuator and control port X connected to port A. The calculation provides a starting point for vin the right orifice for the application.
This flow control maintains a constant flow across the cover poppet, independent of the main flow dni B P1 to A P2thereby providing pressure stability at all system flow rates. See table on previous page. Covers, inserts, pilot valves, modules, and diin bolt kits must be specified separately. It is this pilot port which pilots the poppet open or closed giving the dynamic feature.
For instance, a cartridge cover can be changed to control poppet time and travel, thus controlling actuator acceleration and speed.
Slip-In Cartridge valve, ISO (DIN )
This pressure must be dun to the pressure setting of the unloader pilot stage to initiate unloading; the system pressurizes again when this pressure drops by approx.
The R insert 1: A typical DG4V-3 S solenoid operated pilot valve starts to pass pilot flow dni 10 ms after it is energized. Pressure Reducing Functions Unlike other cartridge valve inserts, 42342 reducer insert contains a spool rather than a poppet. Turn clockwise to increase pressure setting; counter-clockwise to reduce setting See page for information on bolt sizes, bolt kits and assembly torques Types K and M adjusters Type K: Pilot port Z2 can be used to pilot a second cartridge simultaneously.
Basic poppets are illustrated. Pilot flow passes out of Z1 to an appropriate pilot relief valve which creates pressure on the top of the pilot piston.

Full opening time of the cartridge valve depends on the operating pressure djn the control orifice size used. Speed control in accordance with machine operating cycles or programs. The A insert stroke adjuster cover is available with three types of adjusters, micrometer Mmicrometer with keylock K or standard square end screw with 224342.
Port Y is normally connected to a drain line. The design achieves servo-type control of the main poppet without using an electrical feedback transducer. Normally, with the flow rate through the proportional throttle being less than the pump delivery, excess pump flow will be by-passed through the cartridge insert flow A to B to reservoir.
Z1 A P X Y Type D10 insert has good response combined with low shock characteristics and is recommended for general use. Note that the circuitry i. Faster response — up to four times faster than spool type valves — allows faster machine cycling for greater productivity.
Each cartridge in a system can be sized for the actual flow encountered, optimizing component size and cost. This valve range is ideally suited for applications requiring a prefill valve or decompression valve. At all times flow is possible from A to B.
