System pressure at A PFigures 23 and 24, is determined by manual pilot adjustment.
Non-standard orifice 8 Mounting bolts requirements should be defined as follows: Drain port Y is always connected directly to the reservoir. Thus by controlling flow through the pilot valve, the main poppet can be controlled in any position from fully closed to fully open.
XRa t4 t5 min. Difficult environments could mean that extra screening may be necessary to avoid the interference.
It varies flow to provide a constant outlet pressure below that of the inlet pressure. See inserts model code on page The D16 insert is not to be used as a pressure control such as relief or counterbalancing. Other orifice sizes and locations can be fitted by special arrangement with your Vickers representative.
NG 16 – NG The X port is the pilot pressure port. If the outlet pressure exceeds inlet pressure when the pilot valve is closed, the main poppet allows reverse flow see CVCS model codepage Page 20 20 20 21 21 22 22 27 27 Solenoid controlled, pilot operated models 2-way, 2-position; single- and double-solenoid control; sizes 16 to Sizing of control orifices is key to tuning the relative response of each cartridge unit.
Sizes 16 to 40 The pilot valve can be any of those charted below, depending on the working pressure involved. See page for Single or double solenoid pilot valves are applicable.

The main spool consists of a sleeve with a sharp edged seat and a piston. Omit W from model code positionsee page The Z1 port is used for remote control of the reduced pressure. Kit contains three of each orifice and plug indicated.
In Figure 54 flow is not dim from B to A. The dun would have pump flow going into port B, port A connected to the actuator and control port X connected to port A. For additional information, request catalog Thus, for example, four cartridge valves are required to replace a typical three position, four-way spool valve Figure 1. Pilot flow passes out of Z1 to an appropriate pilot 24324 valve which creates pressure on the top of the pilot piston. Often, the most economical system incorporates combinations of manifold mounted spool valves and screw-in and slip-in cartridge valves.
Port Z1 should be blocked when not required. XRa t8 2 0. A suitable remote control is the CGR valve. Operation of both types D10 and C10F is similar: This pressure must be equal to the pressure setting of the unloader pilot stage to initiate unloading; the system pressurizes again when this pressure drops by approx.
The inserts are offered with the three springs L, M and H, and the cover comes with or without a stroke limiter. As the upper area of the poppet is greater than the area facing the inlet 1the poppet is held against its seat 6 by a force proportional to the difference between valve inlet and outlet pressures. Low hysteresis, fast response option: Check Valve, Slip-In Cartridge, for mineral oil or water.
Adjustment of valve setting is only possible while key is inserted and turned to engage driving pin. Sizes 25, 32 and 40 are supplied as separate insert and cover: Cartridges can be easily serviced without disturbing system piping, thereby increasing machine uptime and reducing maintenance time and costs.
Each cartridge in a system can xin sized for the actual flow encountered, optimizing component size and cost. Replace bolts and torque to 7—9 Nm 5.

For sizes 80 and see page CVGS P These six modules were designed to satisfy the needs of Vickers application and systems engineers in providing effective solutions to a wide variety of pilot control requirements in cartridge valve systems. Installation dimensions unaltered for design numbers 31 to 39 inclusive. Sizes 16 to 63 Sizes 16 to Sizes 16 to are per DIN standard The inserts have an area ratio of 1: Faster response — up to four times faster than spool type valves — allows faster machine cycling for greater productivity.
Hydraulic position feedback is obtained by providing the main poppet with a longitudinal slot 5 in its cylindrical surface.
Adjustable stroke limiter; uni-directional control.
