Pilot flow passes out of Z1 to an appropriate pilot relief valve which creates pressure on the top of the pilot piston.
Mounting bolts supplied for sizes 16 to 40 only. As this occurs the slot passes the metering edge 7opening the variable orifice and allowing flow through the pilot circuit.
Engineers faced with a system design problem should consider all possibilities before deciding on a particular solution. Note that any pressure in port Y is additive to the setting s of the integral pilot pressure control s.
Pilot mounting interface offset by 11,0 0. Additionally, venting, unloading, and remote piloting are possible. Turn clockwise to increase pressure setting; counterclockwise to reduce setting See page for information on bolt sizes, bolt kits and assembly torques X Types K and M adjusters Type K: Omit W from model code positionsee page 243422 Electrohydraulic proportional control of pressure is also available.
As above but using a model R insert area ratio 1: B A B T Operating characteristics of cartridge valves can be altered easily to fine tune the motions of a machine. Installation dimensions unaltered for design numbers 31 to 39 inclusive.

D poppets cannot be used for flow from B xin A. Non-standard orifice requirements should be defined as follows: Flow in the opposite direction B to A is prevented by connecting port B to the full poppet area AAP, via drilled holes on the poppet, whereby any pressure at port B assists the spring in holding the poppet hard on to its seat.
An electrically modulated proportional pilot is dni that can provide infinitely variable reduced pressure settings and a vent condition. System components must be ordered by complete model numbers. All Vickers valves undergo full fatigue and endurance tests before dun. Absence of spool seals improves reliability. 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.
The area ratio of the large piston to sleeve seat is 1: With X connected to B, system flow is from A to B.
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. At both of these positions the main flow path A—B is closed. Pressure on the AP area, plus the spring force, holds the poppet against the seat. The shuttle directs the higher of the pressures at the X and Z1 ports to the spring area AP of the insert poppet to close it.
Setting-up and 243342 diagnosis eased by panel display and signal monitoring points. Damping can be achieved with a model R16 insert area ratio 1: Further fine tuning to suit particular system requirements can be achieved by changing orifice sizes.

Reliability Cartridge technology proven over several decades of use. To obtain a D insert with an orifice in the poppet i. Apply a thin coating of Loctite grade or equivalent to the internal thread only.
Amplifier Designed for zero leakage when closed. With seals on the poppet which eliminate internal leakage, ensuring pressure is maintained in dn port A. If there are pressure surges in the B port, the Y port should be directly drained to the tank through a separate line. Side Z1 Orientation pin Type K: 2432 position feedback is obtained by providing the main poppet with a longitudinal slot 5 in its cylindrical surface.
The insert used can be either the model D16 1: Sin the R also for any check or directional function where a D20 insert is ordinarily used.

Solenoid Orientation 12 NG63 approx. For some functions, inserts and covers are supplied as a unit complete assembly ; e. Sizes 16 to 40 The type DC16 insert is used with the type B cover to provide a direct check function, Figure 9. Pressurizing port X from a remote source will block flow from insert port A and B. This valve is used for pressure control. Cover types A and N only. A Typical applications for unloader functions are:
